Re: Latest RPG Updates

[Peter Dow <petercdow@xxxxxxxxx>]

Jon,

Assuming the FORMAT procedure and its candidate procedures are all in a 
service program, how do I use it in another RPG program?  I would guess 
that I have to put the prototype in the RPG program, yes?  Do I have to 
put all the candidate prototypes in there too? My thought was the RPG 
program using it would simply have

Dcl-Pr  Format  Override( ProcA, PgmB, JavaC );


but now that I put it that way, the compiler would have to go to the 
service program to check my usage against each of those candidate 
prototypes to see if it's allowed.
