One is set, the other is not and you're passing the one not set.


There's an annoying "feature" of RPG where RPG will automatically define the basing pointer used in the BASED keyword, if the pointer is not already defined. At least, I find it annoying.

If you use the BASED keyword in a subprocedure and code a global pointer as the parameter, RPG will "helpfully" define the pointer locally. So even though you think you have only defined the pointer once, the compile listing will show that it is actually defined twice.

The most usual symptom of this is that when the based variable is used in the subprocedure, it fails due to pointer-not-set.

dcl-s p pointer;

dcl-proc;
dcl-s fld char(10) based(p); // causes P to be defined locally!
end-proc;
