Hello,

I'm surprised... I never put the MAIN() keyword in my CTL-OPTs.
Just NOMAIN in my SRVPGM.
My programs are compiled in CRTBNDRPG, that's probably the reason. I never use CRTPGM. Yes, I know, I must go to pure ILE structure but...

Hi all,

I've just helped out a very experienced colleague with a program that just wouldn't run. In debug it halted at **free. It showed status RUN in WrkActJob eaiting quite some CPU. In the call stack it stopped just past program entry point _QRNP_PEP.... We were not even able to force it into an error with the wrong number of parameters.
After a couple of hours testing we found that the ctl-opt main() keyword was missing.

I would say that the compiler should have been able to tell us about this situation or that it could have just ungracefully failed runtime.

Just out of curiosity: is there a reason why a program with this condition does indeed compile and can be called without failing?

Thank you for any shared thoughts


Kind regards,
