We are using PowerBuilder communicating with ADABAS on a mainframe through a CICS layer of procedures (But there is a blackbox that sits between PowrBuilder and CICS)...

Is there a tool that can connect PowerBuilder to CICS directly on the mainframe?

Hi Sufyan;

  The last time that I worked on that type of configuration, I was using an IRMA board in the PC that emulated a 327x terminal. Then an IRMA DLL that I called from PB to scrape the 327x buffer and drop the data into a DWO. Then on the way back to CICS, scrape the DWO changed column data  & then place that back into the 327x buffer, then emulate pressing the Enter key on the 327X device (via IRMA DLL calls).

FYI:  https://en.wikipedia.org/wiki/Irma_board

  • How is your environment configured?
  • Do you have some kind of 327x terminal emulator software that is being used?
  • Is that the "Black Box" that you refer to a 327x emulator?
  • Do any of these mechanisms have a callable API?

Note in order to talk directly to CICS on the mainframe, you would need to have PB talk native VTAM.
