Hi,

I have a COBOL-IMS program. I want to pass a parameter (say a date field) from JCL. The mode of IMS call in JCL is DLI. How do I pass the &date from JCL?

What kind of change I have to make in the application program? Will 'ACCEPT' verb get the parameter?

Thanks in advance for your help.

Hi Kolusu,

Ofcourse I did a search before I raised the question in this forum. I know how to pass the parameters to a COBOL-DB2 Program. The question here is "how to pass an user parameter thru PARM to a COBOL-IMS program". I am very aware that there is a workaround to achieve the result by using files. In my case it will be very appropriate if I use PARM parameter.

The parm for DFSRRC00 is as below:
Code:

PARM=(DLI,&MBR,&PSB,&BUF,&SPIE&TEST&EXCPVR&RST,&PRLD,&SRCH,
     &CKPTID,&MON,&LOGA,&FMTO,&IMSID,&SWAP,&DBRC,&IRLM,&IRLMNM,
     &BKO,&IOB,&SSM,'&APARM',&LOCKMAX,&GSGNAME,&TMINAME,&RRS)


Here I hope we can use the symbolic APARM to pass the parameters. Is that correct? If so, how to accept or read this parm in the COBOL application program?

m. kamalhasan,

*sigh* You cannot pass values to IMS pgm via Parm parameter. So you need to use ACCEPT verb in here. In your JCL code the following.
Code:

//SYSIN  DD *
  your parms here


Now in your pgm use the ACCEPT verb and it will pickup the values passed via sysin.

Hope this helps...

Cheers
