Cobol compile failed for Tax Update 21-B and 21-C COBOL files from HCM Image 39
Our production is on HCM Image 37 and PeopleTools 8.57.05 . Our COBOL Compiler is MicroFocus NetExpress 5.1 . When we created and applied our change package for Image 37 we were still good using NetExpress 5.1 to compile the COBOL programs delivered from Image 37. When we created and applied our change package for Tax Update 21-B and 21-C from Image 39, we had error compiling the COBOL programs delivered from Image 39.
I understand the official support for NetExpress 5.1 is expired by end of April and we should start to use Visual COBOL. But I would still like to understand the cause of the COBOL compile failure. Is that because COBOL program from Image 39 (PeopleTools 8.59.02) is no longer compatible with NetExpress 5.1?
