Here's a stripped out module. Just an example. You will know what to work
with binding directories. You can name the source to this anything you
want and add as many procedures you want. To compile this source, you will
need to use option 15 in PDM (CRTRPGMOD). Then goto WRKBNDDIR and add the
source of this module to a binding directory of your choice.
Then in programs that you want to reference this procedure, you will need
to bind the procedure to that program. Which can be as easy as using the
HSPECS and entering the Procedure Prototype to that program.
In the calling program,
H BNDDIR('BNDDIR')
D PROTO_02 PR 15P 5
D num1 15P 5 Const
D num2 15P 5 Const
/free
answer = proto_02(1, 2);
/end-free
Module holding the procedure (name the module anything you want)
h Option(*NoDebugIO)
h NoMain

Please respond to

<rpg400-l@midrang

Okay, the following code snippet works.
D PROTO_02 PR
D num1 15P 5
D num2 15P 5
D PROTO_02 PI
D num1 15P 5
D num2 15P 5
D num3 S 15P 5
/free
num3 = num1 + num2;
dsply num3;
dsply 'DONE';
*inlr = *on;
/end-free
Can somebody please give me an example of how I could call this function
from an outside program. Can it be done like Michael suggested:
DIFFPROG.RPGLE
/free
var3 = PROTO_02(5:6);
dsply var3;
//var3 would have 11.
//ofcourse var1, var2, var3 are already declared as 15 P 5(I surmise it is
a
language necessity).
/end-free
I was also wondering if somebody could give some sample code for a simple
subroutine program. For example a subroutine which takes two numbers and
gives out the product.
Thanks for all the assistance.
Jake.
