Re: ChapGPT
Just as an off-topic disclamer, teaching cobol to a IA is never a good idea (take Terminator as an example). Also, I use GOBACK on rutines, STOP RUN on programs. Let's say MAINPGM calls MAINRTN, then

Re: How to wait indefinitely for a read on CTC device?
Jay, Yes true.? But ACF/VTAM 4 and above supports multiple CTC connections in pairs. No reason not to use the same approach at the TK4 level if you are in control of reading/writing to the hardware.
