Re: Calling a function with undefined/unlimited number of parameters

[James Perkins <jrperkinsjr@xxxxxxxxx>]

I would just send them all as strings. In fact, I would probably just use 1
string parameter (probably a pointer with options(*string : *trim). Then in
RPG use the %EDITC() or %CHAR() BIF to format it myself.

RPG does not understand VarArgs, so there is no point, IMHO, in creating a
subprocedure for every possibility.
