Re: Calling RPGILE program from C

I am building a trigger mediator and recursion is the issue. As a side note
Charles Wilt's note '...at v5r4 RPG programs aren't reentrant...' surprised
me. At what release are they reentrant?

Anyway, I looked at Alan Campin's code. It seems really convoluted.
Wouldn't a pass thru C program calling a SRVPGM proc do the same thing?

John, what do you mean by 'direct'?
