I was recording a VSCODE for IBM i video this morning, talking about the different ways of storing our RPGLE code as a bound RPGLE program, or as separate modules which are then bound into a program with the CRTPGM command. So, I accidentally wrote this description of OPM vs ILE and realized that it …
What is an IBM i PATH? In PASE (Portable Application Solutions Environment), $PATH is an environment variable that stores a list of directories where the system searches for executable files, such as commands and programs. The PATH is like a *LIBL for open source. Just like library lists, the PATH setting only exists during our …
