Re: Anybody got any experience calling the C "printf" function from RPG?

James,
 
Another option is to use the Qp0zLprintf ("Print Formatted Job Log
Data") procedure - it's the external version of printf(). It accepts any
number of parameters - the first is the main string and then the others
are the substitution variables. I have it defined as follows (with 10
non-passable parameters, but you could define more or less):

D WriteToJobLog   PR            10I 0 ExtProc('Qp0zLprintf')        
D  Message@                       *   Value Options(*String)        
D                                 *   Value Options(*String:*Nopass)
D                                 *   Value Options(*String:*Nopass)
D                                 *   Value Options(*String:*Nopass)
D                                 *   Value Options(*String:*Nopass)
D                                 *   Value Options(*String:*Nopass)
D                                 *   Value Options(*String:*Nopass)
D                                 *   Value Options(*String:*Nopass)
D                                 *   Value Options(*String:*Nopass)
D                                 *   Value Options(*String:*Nopass)
D                                 *   Value Options(*String:*Nopass)

It simply writes the data to the joblog (as the name suggests). Very
simple.

HTH,

Rory
