Posted: Fri May 04, 2007 3:44 am Post subject: BMS Map Compilation To Include Cobol Copybook
Hello,
( 1) May I check with experts like u on whether we can include a Cobol copybook in a BMS source and subsequently have it compiled into a Cobol copybook and a map load module?
( 2) If it is possible to include a Cobol copybook in the BMS source, what's the syntax? Is it Copy "copybook name"?
( 3) Pls advise.
Thank you and have a nice day ahead.

a COBOL copybook contains either data definitions or procedure statements in COBOL syntax used to build a COBOL source program; they are introduced into the source stream via the COBOL Compiler directive: COPY
FROM the CICS Appl Pgm Guide:
Quote:
Basic mapping support (BMS) is an application programming interface between CICS programs and terminal devices.
BMS syntax is different than COBOL, so attempting to assemble a map that included COBOL syntax and BMS syntax would probably not fly.
here is a good place to start reading about BMS _________________ Dick Brenholtz

( 1) Thanks for your advance.
( 2) However, 1 of my teammates has the thought of using the statement "COPY XXXXXX" where XXXXXX is another BMS map. His reason for using is that the bottom (line 20 to 24) of about 10 screens are the same. This map is included in the SYSLIB during generation of the map copybook and load module.
( 3) Is it acceptable?
Thank you.

If you cannot find a something like what you want in the manual then the answer is 'NO' _________________ Utility and Program control cards are NOT, repeat NOT, JCL.

Sounds to me like you are having problems finding any "experts"....
The BMS source is used to create the BMS CSECT needed by CICS to generate and parse the screen image and the COBOL or Assembler DSECT needed by your program to access the fields of that screen image.

Just specify the LANG when you assemble the TYPE=DSECT and you will get the output needed for your copybook.

CICS Guy: my understanding is not the generation of the copybook but he wants to include common BMS source into his BMS sources by some means similar to the COPY and INCLUDE statements for copying commone source into Cobol and PL/1 programs. _________________ Utility and Program control cards are NOT, repeat NOT, JCL.

though inefficient in terms of processing, i've been in shops where the header and trailer (top 1 to 3 lines and bottom 4, 3?) maps were 1 standard map and the body (program) -lines 3 or 4 to 19 or 20,21... - was a third. After the initial send map of the header and trailer, only the header need be sent if there was a change in the data - time, page , etc... the trailer was only sent once............ _________________ Dick Brenholtz

We use assembler macros to define the common code at the top and bottom of our maps. Since the BMS source code is all assembler macros anyways this just saves a lot of time and trouble coding the maps and keeps all the maps the same where they need to be.

That, I think, is what the guy wants. Now he will need the A, B, C of how to do it. _________________ Utility and Program control cards are NOT, repeat NOT, JCL.

This is a macro that will produce the first 2 lines of the map. Line 1 has a screen id in the left side a heading center on the line and two fields on the right side for the current date & time. The second line has a field for the program version on the left, a field for LOC (locality), OFF (office), office name.
( 1) Thank you very much for your advice.
( 2) Can I conclude that the word "COPY" is invalid in BMS source?
( 3) The way to include other BMS source is to use MACRO like the 2 examples above.
( 4) However, may I check with CraigG, the BMS source as in the 2nd example, after adding in the macro for the 1st 2 rows of the screen, the rest of the screen definition (row 3 to 24) we can put our codes under this BMS source, right?
( 5) Thank you very much to all of u all.

( 2) Copy is not valid in BMS source, BMS source is assembler not cobol.
( 4) Yes you would code the remainder of your screen definition after the screen1 macro invocation. The screen1 macro would be in a PDS that would be included in SYSLIB in your BMS assemble jcl.
