Ummm... but as you point out, that's only one parameter. The question was how many parameters can you have, not how many items in a data structure.

Heck, you could pass a pointer to a linked list and have a virtually unlimited number of items in one parameter. (The only limit would be the number of simultaneous allocations supported by the operating system, or the amount of storage on your system, which are very large numbers.)

But since the question was "how many parameters" the answer is 255 for a program, and 399 for a procedure.

Though, the most parameters I've ever seen passed to a single RPG program was 51 -- and I though that program was very poorly designed for requring that many parameters. It should've been a service program with multiple entry points.

Using the Unix paradigm (or Qshell) I can see wanting a lot of parameters, but with the standard i5/OS paradigm, I just can't see why you'd ever need more than 20 or so.
