    Is this the right way to get current time into a numeric variable in free-form RPG?
     Time=%subdt(%time:*h)*10000+%subdt(%time:*mn)*100+  %subdt(%time:*s);

    Let's take the expression atoi(%char(%time():*iso0)) step by step: 1) %time() returns the current time as datatype time. 2) %char(%time():*iso0) converts the value from datatype time to datatype character, converting to time format *iso0, which is the time without any separators. You get a string of six digits this way. 3) atoi() converts the character value to numeric. Option options(*string) on the prototype converts an RPG character value to a pointer. The pointer points to a temporary variable containing the string value with null terminator. Got it?

    I wouldn't have used atoi() in that example if it weren't possible. You just need to code two other things in your RPG IV program. First, code bnddir('QC2LE') on your H-Spec. Second, you need to code a prototype for atoi(). The prototype looks like:
     D atoi pr 10i 0 extproc('atoi') D str * value options(*string) 
    Any function in the C run-time library is at your disposal, whether or not you have a C compiler installed on your system. To determine how to write the prototype in RPG, refer to the information at Converting from C prototypes to RPG prototypes.

    Hans, will that get HHMMSS or just HH into TIME? How did you get the address of %CHAR(%TIME()) into the ATOI argument? What is *IS0O ?

    Hans, forgive the newbie question, but are you able to use the atoi function in an rpg pgm? ... if not, how would you use access the function from an rpg pgm?

    That's one way of doing it. But that involves calling %time() three times. If you're unlucky, the time returned each time may be different. For example, the first call might return 12.59.59, the second and third might give you 13.00.00, resulting in a value of 120000. Probably not what you'd want. I'd prefer coding something like this: time = atoi(%char(%time():*iso0));
Working...
