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...….

Thanks
1. I was able to invoke PL/I program using CICSrequest Node
2. Problem is with creating data structure using DFDL to pass on Commarea. |

I did some PL/I coding in the 1990s. It was selected as the code base for a multi-platform product. We wrote a language translator to convert PL/I source code to C. In case you are not familiar with this fairly obscure legacy language, check out the "PL/I Primer" from 1965  Like COBOL and FORTRAN, there are still plenty of active PL/I apps out there.

I recall once owning that primer. It sat proudly in my college bricks and boards bookshelf. Likely tossed it along with Autocoder doc. Yes, that old.
