; This file contains the support code for the $TEXT macro, which
; is responsible for formatting all static string and variable type
; output. For a more detailed explanation of the $TEXT macro, please
; refer to the GLXMAC and GLXLIB modules.
; This module differs from most members of the GLXLIB family in two respects.
; First, it is called via a pseudo instruction, $TEXT, rather than
; via the usual S1/S2 accumulator calls. Secondly, all ACs are preserved
; across calls, which are skippable.
; The user of the $TEXT instruction must provide one or several output routines.
; This routine must conform to the standard GLXLIB conventions.

SUBTTL Revision History
COMMENT \
Edit SPR/GCO Explanation
---- ------- ---------------------------------------------
0001 First attempt
0002 Convert to new OTS format
0003 Make multiple levels work
0004 Add PRO2 and PROQ
0005 Add PROB and PRO1
0006 G013 Add PRON/PUTN
0007 G014 FIX BUG IN ^I OF SPACING CAUSING SPACING TO
HAPPEN TWICE.
0010 FIX BUG WHICH DID NOT ALLOW THE
FIRST PARAMETER IN $TEXT MACRO TO USE
INDIRECT AND INDEXED ADDRESSING. THIS MOD NEEDS
ONLY TO JFCL 1 INSTRUCTION IN X.
0011 CHANGE T%INIT TO USE IIB SET UP BE I%INI1
0012 Add ^R for Job Info blocks and isolate PUTU for
Displaying User Info.
0013 Add STOPCODE IJU for Bad User Info in JIB (^R)
0014 Change ^R Display
0015 Convert to use I%JINF Routines
0016 Fix ^R on -10 with 0 second name word
0017 Fix ^N to Handle SIXBIT on the -10
0020 Make IQN $STOP give bad index, addr of error
0021 Make BTA $STOP give a hint of where we went south
0022 Removed usage of PJUMPE opdef
0023 Have ^E on the -20 accept 20 error codes and expand
them. Those are codes greater than 600000
0024 Allow Indexing and Indirect references for ^Q
0025 Generate Stopcode on invalid ^E function value
0026 Generate asciz pointer for ^Q if size and
position weren't set in fetched pointer.
(i.e. allow ^Q/KEYTAB(S1),LHMASK/)
0027 Change ^E to get dynamic buffer area and have -2
represent the last TOPS20 error.
0030 Fix -10 ^B to Check Node name and Number to decide
if at same node
0031 Modify PROB (Object Block Processor) so that if the
object type is .OTMNT then the unit is put out as a
sixbit value.
0032 Output Date/Time internally instead of using ODTIM.
0033 Convert CNTDT to accept and return arguments in S1 and
S2
0034 Change PUTU so that if the DIRST fails (-20 only),
we will put out 'User Unknown' instead of stopcode'ing
0035 Fix a bug. Initialize LINPTR in $TEXT init code.
0036 Save and restore CAFLG around call to
process qualifier.
0037 Move CNTDT to GLXSCN along with CNVDT
0040 Fix a bug in T%TEXT so that default IB routine
is used if caller doesn't specify one.
0041 Call CNVNOD to do node conversions
0042 Zero out our own $DATA space on init call
because GLXINT no longer does it.
0043 Don't print null paths (as in [10,3572,,,,,])
0044 Better fix to path printer (prevents [10,3572,A,B,,,])
0045 Missing PORTAL.
0046 Clean up messy TOPS-10 user name output in ^R display.
0047 Prevent race where AC 'P' may not have a good PDL
pointer and we get an interrupt. Turn off the PSI
system before doing effective address calculation
and turn it back on when we're done.
0050 16-Nov-81 Comment out the code for the PSI system being turned
on and off and leave it to the discretion of each
sight wether to turn it on and incurr the overhead.
0051 G1216 Edit 34 prints 'User unknown' when DIRST JSYS fails.
Likewise for the -10, if the PPN is zero type 'PPN
unknown'.
0052 31-Jan-83 Fix Batcon IST stop codes.
0053 8-Apr-83 Correct error in edit 52.
0054 Correct non problem coding error.

; %L1:
;Where: Flags tell us whether qualifier takes any argument
; and whether position and spacing words are present.
; The spacing information is: "CHAR"B6+<SIDE>B17+<Number of positions>B35
;

; CAFLG is the flag word for this argument
; CAPTR is the optional pointer word, used to get only a byte from the
; word containing the argument.
; ARGADR points to the word immediately following this argument in the list
; USRACS contain registers 0-17 inclusive of the caller's ACS
; USRRET contains the address of the first word not part of this $TEXT's
; argument block. It is used to calculate the end of the T%TEXT arg block.
;USROUT contains the address of the user routine for
; outputting each byte The supplied routine takes its byte as
; 7 bit ASCII, right justified in AC S1, and returns either
; TRUE or FALSE. A return of FALSE will cause a STOP CODE to
; occur. The output routine supplied may destroy both S1 and
; S2, but must preserve all other registers.
;Each of the following routines is named 'PROx' where x is
; the letter or digit corresponding to the $TEXT qualifier
; that follows the '^' (up-arrow) to indicate that this type
; of output is wanted.
