HI,
I have to modify a JCL in a particular place using REX...
My JCL is as follows
//Chweety PROC MSGOUT='*',QDUMP='*'
//*
//*
//*
//***************
//** Chweety1 **
//***************
//*
//Chwwety1 EXEC PGM=******,REGION=5000K,
//* PARM='UPDT,YYMMDD'
// PARM='UPDT,100602'
//SYSUDUMP DD SYSOUT=&QDUMP
//DSPLEX DD SYSOUT=&MSGOUT
//SYSOUT DD SYSOUT=&MSGOUT
//DSPLD DD SYSOUT=&MSGOUT,
I need to change the PARM value (Which is highlighted in RED color) here with current date. format should be YYMMDD
Note : We cant achieve this by doing "C ALL" as the date changes every day.
I have seen a similar posts by mainframebegginer but that post was incomplete. i did't get anything from there.
Can anyone please help? |

usually the best way to implement these jcl changes is to use the symbol substitution facility of Your scheduling product
fast, effective, no need to write any code,
You only have to ask Your scheduling support telling the rules |

Thanks sorichetti for your valuable response.
Yes, you are rite i can do that. but there are some other PS files which needs to be updated with current date.
Can you please guide me in doing these changes in JCL? i m just curious about this and want to learn some tricks. |

Rather straight-forward, presuming that you've read the contents of the JCL into a stem variable named jcl.
| Code: |
/* REXX */
...
Parse Value Date(O) With yy"/"mm"/"dd
Do z = 1 To jcl.0
Parse Var jcl.z slash parm "'"theparm"'" .
If slash = "//" & parm = "PARM=" & Left(theparm,4) = "UPDT" Then
Do
jcl.z = "// PARM='UPDT,"yy""mm""dd"'"
End
Say jcl.z
End

wowww ... seems like you have solved this in seconds Superk.....
one thing is not yet clear for me...."presuming that you've read the contents of the JCL into a stem variable named jcl" .... what does this actually mean?
Contents ..Can you please tell me what do you mean by contents? |
