What I would like is some general instructions on how to properly define variables in my prototypes for system API calls. For example, I am working with QSZRTVPR API and it has the following format:
1 Receiver variable Output Char(*) 2 Length of receiver variable Input Binary(4) 3 Format name Input Char(8) 4 Product information Input Char(*) 5 Error code I/O Char(*) Optional Parameter: 6 Product information format name Input Char(8) What I would like is something that says: Binary(4) maps to 10I Char(*) maps to (? don't know) Char(8) to 8AAlso whether or not the value keyword is needed. Anything special for I/O vs Input or output. That kind of thing.
Yes, this is basic stuff and yes, I suppose a properly trained RPG programmer would know this stuff, but I recently transitioned to RPG IV (free form mostly) and some of this stuff is just tough to get your arms around (especially when Java and C++ also intrude into the programming mix on a daily basis).
Perhaps an FAQ entitled "How to prototype and use system API's"? Although I know we can't document all the API's, general "rules" about how to do it would be helpful. Perhaps it is already in a post. If so I'd gladly format them into an FAQ or stuff them in the Wiki.
Seems that I have seen something like this somewhere in the past...if so, sorry for the waste of time...could you point me to it.
