RPG Built-In Functions %BIF

When IBM introduced RPG IV (RPGLE) back in the mid 90’s, most of the RPG III opcodes were converted into built in functions. This makes for more readable code and efficient programming. The built in functions each do a particular function just like any opcode would have done. Since the built in functions are provided […]

User guide to the JBA System21 application on the AS400

I found this old email tucked away in a dark, damp corner of my old desktop. Covered in cobwebbs, sticky with splashes of Jolt Cola and sticky bits of snickers bars it raised a wry smile whgen I read it. A quick cut/paste later and here it is. I sent this to some of my AS400 team members when on site for a client in London. A big German bank who’s name rhymes with… erm… well it doesnt rhyme with anything actually.
