Hi,

This is my first post to the forum.
Can anyone let me know what are parser programs ?
And How are they related to CICS transactions?
In case if related , if we are deactivating any CICS transaction from CICS region ,do we need to delete these parser programs as well?

Thanks,
Deepthi

Deepthi,

A parser is nothing but an analysis of the operands entered with a command in addition to the creation of a parameter list for the command processor. It can also refer to the initial processing of source code by a compiler, when it divides up each program statement into its component parts, also known as tokens. ex: xml parser.

You need to clear on what type of parser you are talking about. Take a look at the sample xml program here

Hope this helps...

Cheers

Thanks Kolusu.

Actually, i was doing an analysis on the task of removing some cics transactions from test region.Till now i was under the impression that the components that needs to be removed for the same will be online programs and the maps related to the screens and the screen definitions.Today i got to know that every time we recompile a program in test and test the screen in test, a assembler parser definition will be created for the same. And this also needs to be removed along with all other components.This parser program takes care of mapping the values entered in the screen to the maps.

Please correct me if i am wrong as i am not sure of this.

Also,Could you please throw some light on this?

Thanks,
Deepthi

Is this possible the generation of the DSECT? Here is the JCL we use:

//DSECT EXEC PGM=ASMA90,PARM='SYSPARM(DSECT),DECK,NOOBJECT'
//SYSLIB DD DSN=CICS.SDFHMAC,DISP=SHR
// DD DSN=SYS1.MODGEN,DISP=SHR
// DD DSN=SYS1.MACLIB,DISP=SHR

Bithead,

I believe that JCL you show is used to compile the assembler macro's for CICS Screens. Back in the days when SDF(Screen Definition Facility ) is not available, all the cics screens are written using Assembler macros.

Kolusu,

Did you mean this 'LIST' option while compiling?

//LINK EXEC PGM=IEWL,COND=((5,LT,COB2CICS),(4,LT,PRECOMP)),
// PARM='XREF,LIST,LET,MAP'

Moreover, i am not sure where do these parser definitions get saved when they get created.Can you direct me as to where to check for these assembler level codes that are generated during the compile.This can help me in verifying when i compile the program with NOLIST option.

Thanks,
Deepthi
