Hi All,
I have a requirement wherein ACE (11.0.0.10) has to invoke CICS program using CICSrequestNode. Can someone help with below: -
1. Can CICS request node be used to invoke programs written in PL/I? Or it supports only programs written in COBOL.
2. Can PL/I copy book (not COBOL copybook) be imported to ACE to create message structure?

Any relevant documentation may please be shared.

Thanks

The CICSRequest node invokes CICS transactions. It doesn't matter to ACE what language was used to create the transaction any more than it matters to anything else trying to invoke a CICS transaction. Once source code has been through a compiler and linked, it all looks the same.

Not to my knowledge and this is where you're going to have trouble. It makes no difference to anything invoking a CICS transaction in COBOL, C, PL/1 or Assembler. It makes a huge amount of difference when you try and pass data through COMMAREA (or however you choose to pass it). That is language specific and even after you've had crafted a DFDL model, you'll need to be careful about encoding. PL/1 is odd about it's endian handling.

But it's nice to hear about PL/1. Not written anything in that since the 1980s; nice language with many memories....
