TITLE CPYLIB - COBOL COPY Library Utility Program
SUBTTL D. WRIGHT
;This program replaces the old LIBARY program. It is used to create,
;update and read pieces of COBOL source code stored in a single file
;as a COPY library. The COBOL-68 and COBOL-74 compilers can read
;COPY libraries in this format, as well as the old LIBARY program.

SUBTTL FORMAT OF LIBRARY FILES
COMMENT \
On both TOPS10 and TOPS20, library files have the following format:
!---------------------------!
! "Rough" table !
! always 128 words long !
!---------------------------!
! "Fine" table !
! one two-word entry for !
! each module in the library!
!---------------------------!
! The text in library !
! format (first module !
! immediately follows the !
! "fine" table !
!---------------------------!
Format of "Rough" table:
Consists of two-word entries, one for each 128-word
block needed to store the "Fine" table. At the end of the
entries, the rough table contains all "-1"'s.
Format of "Fine" table:
Consists of two-word entries, one for each module
stored in the library file. At the end of the two-word entries,
there is one "-1" word to mark the end of the directory.
Each two-word entry has the following format:
----------------------------------------------
! First 6 sixbit characters of name !
----------------------------------------------
! XX !S! AD !
----------------------------------------------
Bits: 0 12 13 35
Fields are:
XX = last 2 sixbit characters of name
S = sequenced flag (0= not /S format, 1= /S format)
AD = file word address of start of the module

SUBTTL TOP-LEVEL HELP MESSAGE
;TOP-LEVEL HELP MESSAGE
HLPMST: $TEXT <CPYLIB is the COBOL COPY-file maintenance tool.
Type "R CPYLIB <carriage-return>" to run CPYLIB.
Once CPYLIB is ready to accept a command, it will type the prompt
"CPYLIB" followed by a right angle bracket. You may then type
one of the following commands:
UPDATE library-file <space> output-file
;Read from the specified library file, and write
;a file with the specified output name. If output-file
;is not supplied, the same filename is used.
;You will be in CPYLIB UPDATE mode (see below).
READ library-file
;Read from the specified library file. Do not write
; output anywhere. You will be in CPYLIB Read
; mode (see below).
CREATE library-file
;Create a new library file with the specified name.
; You will be put in CPYLIB CREATE mode (see below).
DIRECTORY library-file <space> output-file
;Do a directory of the library file, and write the
; output to the specified output-file. If output-file
; is not given, the output will go to the terminal.
LIST library-file <space> output-file
;Write a listing of the library file to the specified
; output file. If output-file is not given, the
; output will go to DSK:CPYLIB.LST.
TAKE cmdfile
;Take commands from the specified file.
CPYLIB modes (UPDATE, CREATE, READ)
-----------------------------------
You select one of the three CPYLIB modes by using one of
the top-level commands "UPDATE", "CREATE", or "READ". CPYLIB
gives you a different prompt for each of the modes. You may
type "HELP" once you are in the modes for further information.
Here is a summary of the commands allowed in each mode:
CPYLIB UPDATE MODE:
The prompt will be "CPYLIB Update" followed by two right angle-brackets.
You are then able to specify any or all of the following commands:
REPLACE, INSERT, DELETE, END, EXIT, HELP, TAKE
CPYLIB Read mode:
The prompt will be "CPYLIB Read" followed by two right angle-brackets.
You are then able to specify any or all of the following commands:
EXTRACT, END, EXIT, HELP, TAKE
CPYLIB CREATE mode:
The prompt will be "CPYLIB Create" followed by two right angle brackets.
You are then able to specify any or all of the following commands:
INSERT, END, EXIT, HELP, TAKE
>;END OF HELP TEXT
SUBTTL MORE HELP MESSAGES
;HELP FOR CREATE MODE
HLPMSC: $TEXT <
In CREATE mode, you are creating a new COBOL library from scratch.
Insert modules in alphabetical order using the "INSERT" command.
For example, "INSERT MODNAM FILE.EXT" will insert the module "MODNAM"
from the file FILE.EXT.
Other commands in INSERT mode are:
TAKE filespec ;Read commands from the specified file
END ;Write out the library file and go back to
; the top level of CPYLIB
EXIT ;Write out the library file and exit.
HELP ;Type this text
>
;HELP FOR UPDATE MODE
HLPMSU: $TEXT <
In UPDATE mode, you are reading from one library file,
changing it by module REPLACEment, DELETion, and INSERTion,
and writing the updated library file back out.
UPDATE mode is analagous to using a text editor which can only go
forwards in the file, looking at one module at a time. Since
the modules in a library are in alphabetical order, you must reference
module names in update-mode commands in alphabetical order.
Commands in update mode are:
INSERT module file.ext ;Insert the specified file into the library
;and call it "module"
REPLACE module file.ext ;Replace the contents of "module" with the contents
; of the specified file.
DELETE module ;Delete "module" from the library.
TAKE file.ext ;Take commands from the specified file
END ;Write out the updated library file and
; go back to CPYLIB's top command level.
EXIT ;Write out the updated library file and
; exit.
WHERE ;Show where in the directory we are. This
; command will type a few modules before and
; after the current position. The current position
; is important because you cannot reference modules
; whose names are alphabetically before it.
HELP ;Type this text
>
;HELP FOR READ MODE
HLPMSR: $TEXT <
In READ mode, you are reading from a particular COBOL library file
but not changing it in any way. The only thing you can do in READ mode
is "EXTRACT" a module (copy it to a file). Modules can be EXTRACTed
from the library in any order.
Commands are:
EXTRACT module file.ext ;Copy the module from the library into the
;specified file
TAKE file.ext ;Take commands from the specified file
END ;Return to CPYLIB's top command level
EXIT ;EXIT to monitor command level
