Does CA Ideal batch (IDLBATCH) allow for any alternate to input SYSIN DD? Is there any way to enter a command or execute a member in a CA Ideal batch job step to override SYSIN DD? (e.g., JCL EXEC PARM, alternate DD, or something tied to the userid?)

Question:

Does CA Ideal batch (IDLBATCH) allow for any alternate to input SYSIN DD?
Is there any way to enter a command or execute a member in a CA Ideal batch job step to override SYSIN DD? (e.g., JCL EXEC PARM, alternate DD, or something tied to the userid?) The reason for asking has to do with enforcing some defaults without making massive JCL changes.
 
Environment:

z/OS

Answer:

No, CA Ideal batch does not have any alternate or program parameter for SYSIN input.
You might consider a JCL override technique. One possible technique is to use JCL "DD DDNAME" JCL and other JCL PROC overrides: 
 
//SYSIN DD DDNAME=&ALTDD 
... 
//ALTIN DD ... 
 
Additional Information:
 
Refer to the "Running in a Batch Environment" section of the CA Datacom® Tools - 15.0 documentation in docops.ca.com.
 
 
"...
//SYSIN DD 
Identifies a data set containing CA Ideal™ for CA Datacom® commands executed (normally //SYSIN DD *, which means immediately following). The CA Ideal™ for CA Datacom® commands are entered in a sequence that simulates an online session. For example, a SIGNON command is the initial command that simulates the signon panel and OFF is the final command.
