.hl1 ^&purpose\&
.b2
The purpose of this document is to explain the migration
process from APLSF to VAX APL which is performed by the tool SFTOVX.
An example is provided to illustrate the process
of migrating APL workspaces and data files. This document also
explains the possible error messages and lists the APLSF/VAX APL
incompatibilities.
.b2
.hl1 ^&explanation\&
.b2
The migration of APL workspaces and data files from APLSF to VAX APL occurs
through text files. MIGRATE, an APL function, builds a batch
control stream which
then executes APL functions that create text files from APL files.
Note that the easiest way to perform the migration in an unattended
mode is by building this batch control stream.
MIGRATE interacts with the user to find out what should be transported and
prompts the user for filenames. MIGRATE also allows
the user to specify an optional filter workspace (containing functions
such as FILTER, ASFILTER, and DAFILTER) which allows the user to modify the
file before it is transported. Files which can be transferred
include workspaces, and /AS, /IS, /DA and /BS data files.
.b
Through MIGRATE, a batch stream is executed which invokes the DRIVER
function to
transfer workspaces, the ASDRIVER function to transfer /AS data files, etc.
Note that when the driver function is invoked to
transfer a data file, its name reflects the type of file it is
transferring (for example, ASDRIVER, DADRIVER).
.b
These driver functions dump the workspaces and data files as input scripts
into text files which are then transferred by the user's own methods
to the VAX. They are then used by VAX APL
as )INPUT files. DRIVER transports variables, system variables,
channel assignments, workspace identifications, groups, and unlocked functions
within APLSF workspaces as text to the VAX. While the text file is being made,
DRIVER examines the user-defined functions to perform source transformations
that minimize the incompatibilities between APLSF and VAX APL.
.b
Note that these
transformations do not occur within literals (for example, arguments to
execute). Any informational messages displayed for the user are comment lines
in the file that is used as )INPUT to VAX APL.
.b
Once DRIVER has generated the text file and the user has
transferred it to the VAX, the user executes an APL function called SUBMIT.
SUBMIT interacts with the user and builds a VMS command file that, when run
indirectly or in batch, will execute VAX APL for each input script specified
by the user. When these input scripts are processed by means of VAX APL,
a workspace or a data file is created on the VAX. These created
files are the migrated images of their counterparts on TOPS-20.
.b
This is a general tool which can be overlaid
by the user's software in certain instances (for example, the FILTER
function).
.b
.nt
DRIVER performs a )LOAD of each workspace being migrated. If the
workspace contains a nonempty .BXLX, the .BXLX will be executed.
This may interfere with the migration process. Note that APLSF has
no facilities to suppress .BXLX when loading a workspace.

.b2
.hl 2 ^&Files in the Migration Tool\&
Several files are contained in the migration tool.
.b;.lm0;.f;.j
SFTOVX contains files for both the -20 and the VAX. The
tools themselves assume that they reside in a directory
with the logical name APLT2V:, both on the VAX and the -20.
The following files are contained in SFTOVX.
.b
.ls 1,"o"
.le;SF2VAX.MEM
.b
SF2VAX.MEM is the documentation for the APLSF to VAX APL
migration tool. It contains only APL TTY mnemonics for
the APL characters. It may be listed on an ASCII printer
for easy access. All APL expressions in SF2VAX.MEM
assume .BXIO is 1.
.b
There are detailed examples listed in SF2VAX.MEM. The
examples are always reproduced in APL TTY mnemonics, even
though some of the files produced by the migration tool
contain APL key-paired ASCII APL characters. Note
that .KM and .KJ are the VAX APL TTY mnemonics for
<carriage return> and <linefeed>. Since the files built for
migration have lines longer than 132 characters, the examples
listed in Sf2VAX.MEM have their lines wrapped to fit on a
printed line. When such wrapping occurs, the line ends with
"<wrap>" to show that it was wrapped for expository
reasons.
.le;BXAV.LA
.b
This is a translation table from APLSF's .BXAV to VAX
APL's .BXAV used by the migration tool. The file contains
APL key-paired ASCII APL character set and therefore
must be printed or displayed on a device that can display
APL characters.
.b
Note the following:
.ls 1,"-"
.le;All of the APLSF .BXAV characters that print as .SQ are translated
into the VAX APL character .SS (.BXAV [210]).
.le;The following APLSF .BXAV characters do not exist in VAX APL's
_.BXAV and are translated into the VAX APL character .CO (.BXAV [211]):
38 (.FI), 121, 103, 113, 115, 116, 117, 122,123 (all internal use
characters). See .LD.USAV below for an explanation of these internal use
characters in APLSF.
.le;VAX APL allows illegal overstrikes in data, in quoted literals,
and in .QQ input. The text files produced by this migration tool
contain APL overstrikes. Therefore, an ASCII backspace cannot be
migrated as a single character because VAX APL will assume it to be
part of an overstrike. Therefore, APLSF .BXAV [99 265] are translated
into the VAX APL character .CC (.BXAV [207]).
.le;Internal carriage return (.BXAV [102] in APL-SF) is
converted to .CC if it is inside a function because .BXBOX
is used to fix text. An internal carriage return inside a
character array is not affected.
.le;There are three overstrikes in VAX APL's .BXAV that are not in
APLSF's .BXAV. If these overstrikes exist as three characters in a
row in the APLSF data being migrated, they will appear as a single
character in VAX APL. These are the following:
.b
#####.CC (, over -)#######VAX APL##.BXAV [207]
.br
#####.SS (.LU over .US)###VAX APL##.BXAV [210]
.br
#####.CO (.RU over .US)###VAX APL##.BXAV [211]
.els
.le;SF2VX0.APL
.b
SF2VX0.APL is built using the text file SF2VX0.IN
as a )INPUT file to APLSF. For example, the following
terminal session builds SF2VX0.APL on the -20:
.b;.ts 12,18
@APLSF
.br
terminal..TT
.br
<APLSF banner>
.br
CLEAR WS
.br
)INPUT SF2VX0,IN
.br
<messages>
.b
SF2VX0.APL is an APLSF workspace containing the function
MIGRATE. MIGRATE interacts with the user to build a
control file that can be run in batch. The control
file performs
the time-consuming task of interacting with the DRIVER
functions that transform APLSF workspaces and data files
into text files.
.b
On the -20, put SF2VX0.APL in APLT2V:.
.le;SF2VX1.APL
.b
SF2VX1.APL is built from the APLSF )INPUT file SF2VX1.IN.
.b
SF2VX1.APL is an APLSF workspace containing the function
DRIVER. DRIVER runs inside an APLSF workspace to transform
it into a text file. SF2VX1.APL transfers the
workspace identification, the file channel assignments, the
settable
system variables, the user-defined groups, the user-defined
functions, and the variables. It also performs certain
source transformations inside user-defined functions in an
effort to minimize incompatibilities between APLSF and VAX
APL.
.b
On the -20, put SF2VX1.APL in APLT2V:.
.le;SF2VX3.APL
.b
SF2VX3.APL is built from the VAX APL )INPUT file SF2VX3.IN.
.b
SF2VX3.APL is a VAX APL workspace containing numerous
user-defined functions that simulate the behavior of
certain APLSF primitives under VAX APL. The source
transformations performed by DRIVER (in SF2VX1.APL)
replace certain APLSF primitives with these user-defined
APL functions:
.ls 1,"-"
.le;_.LD.USEN uses .BXVR under VAX APL to simulate monadic
_.EN from APLSF.
.le;_.LD.USDE uses monadic .EP under VAX APL to simulate
monadic .DE from APLSF.
.le;_.LD.USOM uses B/.IO.RO B under VAX APL to simulate
_.OM B from APLSF.
.le;_.LD.USDQ uses a particular setting of .BXCT under
VAX APL to simulate .DQ from APLSF.
.le;_.LD.USAB sets .BXCT to 0 under VAX APL before
simulating dyadic .AB from APLSF.
.le;_.LD.USIB simulates certain monadic I-beams under APLSF
on VAX APL. The ones that cannot be simulated or are
not supported under APLSF signal an error.
.le;_.LD.USAPPEND, .LD.USDEQ, .LD.USENQ, .LD.USFCM, and
_.LD.USMTP replace the APLSF system functions .BXAPPEND,
_.BXDEQ, .BXENQ, .BXFCM, and .BXMTP. These user-defined
functions report functionality that is "NOT AVAILABLE
IN VAX APL".
.le;_.LD.USASCII replaces .BXASCII from APLSF. It also returns
a vector of 128 characters from VAX APL's .BXAV which
closely resemble the ASCII characters.
.le;_.LD.USAV replaces .BXAV from APLSF. It also returns
a vector of 512 characters from VAX APL's .BXAV which
closely resemble APLSF's .BXAV. See the file BXAV.LA for the
_.BXAV translation table in APL character set.
.b
Note that all of the characters in APLSF's .BXAV that print as
_.SQ are simulated by VAX APL's .BXAV [251]. The following .BXAV
codes in APLSF are not supported and have been replaced by .BXAV [211]:
.b

.le;_.LD.USASS replaces .BXASS from APLSF and reports an
error if its argument contains an APLSF password, a
"ppn" surrounded by square brackets, or the switches
/BS or /DUMP, since none of these are supported in VAX APL.
.le;_.LD.USCHS, .LD.USCLS, .LD.USDAS, and .LD.USFLS replace
the APLSF system functions .BXCHS, .BXCLS, .BXDAS, and
_.BXFLS. While all of these system functions exist in
VAX APL, their behavior in VAX APL on empty arguments
and arguments greater than 100 is different from under
APLSF. These user-defined functions simulate the
behavior under APLSF in these cases.
.le;_.LD.USCIQ, .LD.USCOQ, and .LD.USDVC replace the APLSF
system functions .BXCIQ, .BXCOQ and .BXDVC. While
all of these system functions exist in VAX APL, their
behavior in VAX APL is different from under APLSF.
These user-defined functions report an error that the
specific system function is "IN VAX APL" but is "INCOMPATIBLE
WITH APLSF".
.le;_.LD.USQLD, .LD.USQCO and .LD.USQPC replace the APLSF
system functions .BXQLD, .BXQCO, and .BXQPC. These
user-defined functions check their argument for an
APLSF-style password on the workspace being accessed
and replace it with a VAX APL-style password.
.le;_.LD.USRENAME replaces the APLSF system function
_.BXRENAME. This user-defined function is designed to
simulate the behavior of APLSF's .BXRENAME by using the command
".EP')DO RENAME ..." in VAX APL.
.le;_.LD.USTT replaces the unsettable APLSF system variable
_.BXTT. This user-defined function uses .BXTT in VAX
APL to construct the correct value returned by .BXTT
in APLSF for "terminal type".
.le;Because the user may not desire to perform all of the
transformations, note that the primitives are in TAB3 and their
replacements are in the rows of MAP3. The system function names are
located in TAB4.
.els
On the VAX, put SF2VX3.APL in APLT2V:.
.le;SF2VX4.APL
.b
SF2VX4.APL is built from the APLSF )INPUT file SF2VX4.IN.
.b
SF2VX4.APL is an APLSF workspace that contains the file
drivers, DRIVER, ASDRIVER, ISDRIVER, BSDRIVER, and DADRIVER.
These drivers are used to transform APLSF data files (/AS, /IS,
/BS, and /DA files, respectively) into text files.
.b
On the -20, put SF2VX4.APL in APLT2V:.
.le;SF2VX5.APL
.b
SF2VX5.APL is built from the VAX APL )INPUT file SF2VX5.IN.
.b
SF2VX5.APL is a VAX APL workspace that contains the function
SUBMIT. SUBMIT interacts with the user to build a
command file that can be run in batch that will perform
the time-consuming task of running VAX APL on all of the
text files that have been migrated from the -20.
.b
On the VAX, put SF2VX5.APL in APLT2V:.
.els
.hl 2 ^&Files Built by the Migration Tool\&
.b;.lm0
Several files are built by the migration tool.
.b
The APL functions in SFTOVX produce files that either run other
tools or consist of text that should be transferred from the -20
to the VAX.
.ls 1,"o"
.le;MIGRATE in SF2VX0.APL on the -20
.b
MIGRATE produces a batch control file named MIGnnn.CTL,
where "nnn" is a number from 000 through 999, in the
connected directory. It chooses "nnn" by finding the first
such file name that does not exist.
.b
The workspaces and APL data files on the -20 that are to be
migrated
to the VAX can reside in any accessible directory, as long
as the file is not protected against reading.
.le;DRIVER in SF2VX1.APL on the -20
.b
DRIVER produces a file named "wsid.W2V" where "wsid" is the
workspace identifer of the workspace being transferred.
The .W2V file contains APL key-paired ASCII APL characters.
.le;File drivers in SF2VX4.APL on the -20
.b
ASDRIVER, ISDRIVER, BSDRIVER, and DADRIVER each produce
files named "file.x2V", where "file" is the name of the
APL data file being transferred, and "x" is "A", "I", "B",
or "D", indicating the type of DRIVER that produced the file.
The .x2V file contains APL key-paired ASCII APL characters.
.le;SUBMIT in SF2VX5.APL on the VAX
.b
SUBMIT produces a command file named SUBnnn.COM, where "nnn"
is a number from 000 through 999, in the default directory.
It chooses "nnn" by finding the first such file name that
does not exist.
.b
The VAX APL images of workspaces and APL data files migrated
from the -20 will be constructed either in the default
directory on the VAX or in a directory associated with the
logical name APLnnn:, where "nnn" was chosen by the DRIVER
that produced the text file on the -20. SUBMIT will prompt
the user for the definitions for these logical names.
.els
.hl 2 ^&User-Defined Filters\&
The following describes user-defined filters which handle special migration
difficulties.
.b
MIGRATE allows the user to specify a "filter workspace" to be
executed before the workspace or APL data file in question is
processed:
.ls 1,"o"
.le;Migrating workspaces
.b
The user-specified filter workspace is copied, using
)COPY, into the
workspace and the function named FILTER is executed.
This niladic user-defined function can perform whatever
transformations it wishes on the workspace. To
prevent this workspace from being migrated, it can circumvent
further processing by exiting APLSF via )OFF HOLD. When FILTER
finishes,it is erased, using )ERASE, so it will not be
migrated with the rest of the
workspace. The migration process assumes that FILTER will
remove any objects that are not to be migrated from the
workspace before it completes.
.le;Migrating APL data files
.b
The user-specified filter workspace is copied, using
)COPY, into the
workspace SF2VX4 and the function named "xxFILTER" is
executed, where "xx" represents the first two characters of the
DRIVER that will be executed. ISFILTER, BSFILTER, and
DAFILTER are monadic (as are the associated drivers), where
the right argument is the name of the file being processed.
ASFILTER (and ASDRIVER) is dyadic, where the left argument
is the character set to be used to read the file (1 if TTY,
2 if APL) and the right argument is the file name.
.b
Note that it is important for users to provide their
own version of the xxREAD routine that the xxDRIVER calls
to process the data file, especially if the file being
processed is a /BS file with no headers on the records.
In that case, users are the only ones who know what
constitutes a record in the file. There is
internal documentation of the xxREAD and xxDRIVER functions
in SF2VX4.APL and SF2VX4.IN so users can determine if
they must provide their own xxREAD to migrate a data file.
.b
Several character set conversions take place. .SQ is
converted to .SS. Any element designated for internal use is
converted to .CO. Backspace is converted to .CC and any
internal carriage return within a function is converted to .CC.
.els
.hl1 ^&example\&
Below is an example that illustrates the interaction between the user
and the migration tool. The example is divided into five parts:
.ls 1
.le;MIGRATE running under APLSF
.le;The TOPS-20 batch control file that results from running MIGRATE
.le;DRIVER and the corresponding file drivers running under APLSF
.le;Transfer of text files to VAX by the user's own methods
.le;SUBMIT running under VAX APL
.els
The input scripts, the result of executing a DRIVER, follow
the running of each corresponding DRIVER function. Following each of these
parts, there is a brief explanation of some lines of the script.

Note that terminal output is in uppercase, with APL input indented six spaces.
Annotations are in lowercase.

Incompatibilities exist between APLSF and VAX APL. The
action that the migration tool takes on each of these
incompatibilties is listed below. "SFTOVX takes no action" means
that the migration tool does not identify the incompatibility, nor does
SFTOVX replace it to simulate APLSF behavior. Any transformations done by the
migration tool are reported to the user when the tool runs.
.nt
These transformations do not take place within quoted
literals.
.en
.ls,"o"
.le;Escape mode does not exist in VAX APL.
.b
"@" on input to VAX APL in TTY mode will remain an "@". "@R",
for example, are not translated to .RO.
.b

.b
.le;Tabs in data and in files will remain as tabs. They
are not converted to spaces in VAX APL.
.b
.le;_.Z@ is not recognized by VAX APL as the character underscored delta.
.b
SFTOVX takes no action on .Z@. Underscored delta is output in APL
characters by the migration tool. In VAX APL, .UD is underscored
delta.
.b
.le;In APLSF, .RU is a "U" with the feet pointing to the right; .LU
is a "U" with the feet pointing to the left. In VAX APL, .RU is a "U"
with the feet pointing to the left and .LU is a "U" with the feet
pointing to the right (in other words, the directions of the feet are
opposite what they are in APLSF).
.b
SFTOVX will output the "U" with the feet pointing to the right as "left U"
(.LU) and the "U" with the feet pointing to the left as "right U"
(.RU). The APL graphic from APLSF will be the same as the APL graphic
inside VAX APL.
.b
.le;Dyadic $ is not supported in VAX APL.
.b
SFTOVX converts a $ primitive function to .BXFMT.
.b
.le;Monadic .EN, .DE and .OM are not supported in VAX APL.
.b

_.LD.USOM which simulate their behavior under APLSF.
.b
.le;If A is an integer in A/B in APLSF, it is an error. In VAX APL,
it is the function replicate.
.b
SFTOVX takes no action.
.b
.le;Both monadic and dyadic .DQ are fuzzy in VAX APL but not in APLSF.
.b
SFTOVX replaces the primitive function .DQ with .LD.USDQ,
which sets .BXCT to 0.22204460E.NG15, APLSF's internal value for
singularity testing (established in APLSF v2 in edit 257) before
executing .DQ.
.b
.le;Dyadic .AB is fuzzy in VAX APL but not in APLSF.
.b

which sets the local .BXCT to 0 if invoked dyadically.
.b
.le;Floor and Ceiling apply .BXCT differently in VAX APL than in APLSF.
.b

.b
SFTOVX replaces .BXAV with a niladic function .LD.USAV,

.b
.le;_.BXRENAME may behave differently in VAX APL than it does in APLSF.
.b
SFTOVX replaces .BXRENAME with the user-defined function .LD.USRENAME
which attempts to simulate the behavior of .BXRENAME in APLSF.
.b
.le;_.BXENQ, DEQ, MTP, APPEND and FCM are not in VAX APL.
.b
SFTOVX replaces these system names with user-defined functions,
for example, .LD.USENQ, which executes .BXBREAK '.BXENQ not supported
in VAX APL'.
.b
.le; In APLSF, certain system variables and all system functions can be
localized in function headers or assigned to. In VAX APL these system
variables are niladic system functions so they cannot be localized or
assigned to.
.b
The system names involved are the following:
.b;.ts20,27,34,41,48,56;.nj;.nf
AV ALPHA ALPHAU NUM CTRL LC
AI TS TT UL WA
.b;.f;.j
SFTOVX removes these and all system function names from function header
local lists. It replaces assignment to them with assignment to
'.BXSINK__'. Therefore the only quad names allowed in locals lists are
the following:
.b;.ts20,27,34,41,48;.nf;.nj
AUS IO RL CT TIMELIMIT
SF ERROR PP GAG TIMEOUT
PW TRAP LX
.b;.j;.f
.le;Several system commands in APLSF are not in VAX APL.
.b
The system commands involved are the following:
.ts20,27,34,58;.nf;.nj
MODE TABS LIB and DROP switches BLOT
C CALL CREATE ECHO
R RUN SEAL TIME
.b;.j;.f
For any of these to be used, they would have to be executed, either
with .XQ or .EP. Note that .EP returns 0 21 .ro 0 and .XQ dies.
.b
SFTOVX takes no action.
.b
.le;In APLSF, the shape of the result of .EP')cmd' is a matrix of .BXPW columns
(if the result contains more than 1 row). In VAX APL, the result is a
vector with the rows delimited by CR-LF.
.b
SFTOVX takes no action. Note that .BXBOX in VAX APL converts a
vector of lines delimited by CR-LF into a matrix.

.le;Passwords on workspaces and /DA files are spelled "-password" in
APLSF. The syntax is "/PASSWORD=password" in VAX APL.
.b
Passwords may appear in )LOAD, )SAVE, )COPY, )PCOPY, .BXASS,
)CREATE, .BXQLD, .BXQCO, .BXQPC.
.b
SFTOVX replaces .BXQLD, .BXQPC, .BXQCO, and .BXASS with, for
example, .LD.USQLD
which checks for a "-password" at run-time and change it to
"/PASSWORD=password". SFTOVX takes no action on the system commands.
.b
.le;_.BXTT returns different answers in VAX APL than in APLSF.
.b
SFTOVX replaces the .BXTT system variable with the niladic
user-defined function .LD.USTT. This produces the following
results:
.b;.ts15,40;.nf;.nj
if VAX APL .BXTT is then .LD.USTT returns
.b
2 == TTY 0 == TTY
3 == GIGI 3 == KEY
4 == LA 2 == LA or Tektronix
5 == KEY 3 == KEY
6 == BIT 4 == BIT
8 == VT102-PA/RA 3 == KEY
11 == Tektronix 4013 2 == LA or Tektronix
12 == Tektronix 4015 2 == LA or Tektronix
.b;.f;.j
Note that VAX APL does not support TTYCOM, ONTEL or 2741 APL terminals,
which APLSF does.
.b
.le;_.FM and $ both output "-" for negative numbers in TTY mode in
APLSF. VAX APL outputs "-" only if .BXNG is 0.
.b
SFTOVX does not set .BXNG in the VAX APL workspace since it also
affects .BXFI and .BXVI.
.b
.le;T.LDf and S.LDf set the trace and stop vectors in VAX APL. These
names are valid identifiers in VAX APL.
.b
SFTOVX leaves these as identifiers; the trap and stop settings for
user-defined functions are not transferred.
.b
.le;/BS, /BS* and /BU binary files are not supported in VAX APL.
.b
_.BXASS is replaced by .LD.USASS, which executes .BXBREAK if the
_.BXASS fails. .BXASS reports a "not supported" error message for the
following facilities: passwords, [ppn], /BS, /DUMP.
.b
.le;_.BXCLS, DAS, CHS, DVC and FLS on .IO0 return information on all
12 channels.
.b
SFTOVX replaces each of these system names with user-defined
functions. For example, .LD.USCLS checks to see if its argument
is an empty vector: if it is, it executes .BXCLS .BXCHANS
and returns .IO0 (these functions are not quiet in APLSF). They
also change channel numbers of the form 100+n to -n.
.b
.le;_.BXCIQ and COQ take different arguments and produce different
results in VAX APL than in APLSF.
.b
_.BXCIQ and COQ deal with internal representations, which are different
in the VAX than in APLSF. Therefore SFTOVX replaces these system
names with user-defined functions. For example, .LD.USCIQ executes
_.BXBREAK 'CIQ IN VAX APL INCOMPATIBLE WITH APLSF'.
.b
.le;A trailing "lamp" on output to the terminal suppresses the next CR-LF
in APLSF. It is output simply as a trailing "lamp" in VAX APL.
.b
SFTOVX takes no action.
.b
.le;STOPSET can be trapped in VAX APL. It cannot in APLSF.
.b
SFTOVX takes no action.
.b
.le;APLSF does very little shape-checking on indexed assignment.
.b
SFTOVX takes no action.
.b
.le;The character representation of a number can overflow on the
VAX.
.b
Numbers are transferred as character strings with .BXPP set to 18.
Rounding may cause the string to be a number outside the range of
allowable numbers in VAX APL. A LIMIT ERROR is reported by VAX
APL.
.b
SFTOVX takes no action.
.b
.le;Some functions are quiet in VAX APL, but not in APLSF.
.b
The only function that is quiet that is not being transformed is
_.OQ. This function cannot be replaced with a user-defined function
because it takes an axis argument, which user-defined functions can't do.
.b
SFTOVX takes no action.
.le;_.BXGAG values in APLSF are reversed in VAX APL.
.b
SFTOVX takes no action.
.b
.le;Valid value sets for certain system variables are different in VAX
APL than they are in APLSF.

.le;The integer range in APLSF is from -2*35 to .NG1+2*35. In VAXAPL,
the integer range is from -2*31 to .NG1+2*31. Any integer outside of
the VAXAPL range will be stored as a floating point number under
VAXAPL. The warning "BIG INTEGER IN name" is issued. When using base and
represent to pack small values into integers, the packing may not work
under VAXAPL.

Error messages put out by the various pieces of SFTOVX:
.b
.ls,"o"
.le;MIGRATE in SF2VX0
.b;.ts7
'MIG000,CTL THRU 999 IN USE'
.b
MIGRATE cannot find a file spec of the form
MIGnnn.CTL (where "nnn" is a 3 digit number) to use as
the batch control file it wants to build. Execution
will be suspended at this point - the user can take
remedial action by getting rid of files named MIGnnn.CTL
on DSK: and then typing __.GO .BXLC + 1 to restart MIGRATE.
.b2
The functions MIGRATE and PERFORM in SF2VX0 do not set .BXTRAP, which implies
that software failures will display a message (only the 1st line
since )ECHO is OFF) and suspend execution at the line in error.
The user can then determine how to correct the failure.
.b2
.le;DRIVER in SF2VX1
.b
'SI NOT EMPTY'
.b
This is an informational message only. The SI stack in the workspace being
migrated contains suspended and/or pendent functions. The workspace
will be transferred but local copies of functions and
variables will be dumped out to the input script.
.b2
DRIVER does not set .BXTRAP, which implies that software failures
will display a message (only the 1st line since )ECHO is OFF) and
suspend execution at the line in error. The user can then determine
how to correct the failure.
.b2
.le;The file drivers, ASDRIVER, BSDRIVER, ISDRIVER and DADRIVER in SF2VX4
.b
'ERROR ASSIGNING INPUT FILE: name'
.b
all four drivers display this error if the file is not found
.b
'ERROR n READING FROM FILE name COMPONENT i'
.br
'ERROR n READING FROM FILE name RECORD i'
.b
DADRIVER says COMPONENT; all others say RECORD, where "n"
is an APLSF error number (see Appendix A in the ^&VAX APL REFERENCE
MANUAL\&), "name" is the
file the driver is trying to read, and "i" is the record or
component number currently being read.
.b
This message is then followed by the 1st line of .BXERROR,
which will be the text for error "n".
.b
'ERROR 69 READING FROM FILE name,ADA COMPONENT 0
.br
FILE FORMAT NOT DIRECT ACCESS'
.b
'ERROR 70 READING FROM FILE name,ais RECORD 1
.br
FILE FORMAT NOT INTERNAL SEQUENTIAL'
.b
Processing of the file stops when an error occurs and the output
file (that is the VAX input script) being built is closed.
.b
.le;All drivers check numeric data for integer values that are outside
the integer range in VAX APL. The warning "BIG INTEGER IN name" means
that such an integer was found in the variable name.
.b
.le;While MIGRATE is interacting with the user, recoverable errors
(such as FILE NOT FOUND) are reported and the user is prompted for
alternate input. If the error is not recoverable, the function
suspends so the user can diagnose the failure.
.b
.le;For functions that will most likely be executed in batch (for
example,the drivers), errors are reported and APLSF then suspends execution.
While running the control file built by MIGRATE from batch, the next command
will be )OFF HOLD which returns the user
to the "@" prompt. The user must examine the .LOG file from the batch
job to see if the process was successful. If the function is run
interactively, suspending the function gives the user the chance to
diagnose the problem. Note that if a user-defined filter function is
unsuccessful, the user can debug it if it is being run interactively.
