I have RPG procedures where the first two parameters are alternates, i.e. values must be supplied for param1, param3, param4, etc or param2, param3, param4, etc Using *OMIT I can call these in either mode from RPG, e.g. callp procname(value1 : *OMIT : value3 : value4) or callp procname(*OMIT : value2 : value3 : value4) However I need to call some of these routines from some legacy C code. How do I specify in C (both the prototype and the code) that param1 & param2 can be *OMIT'd? regards Stephen Osborn
