Without further information I'd say:
 
1. It looks like you have over complicated the problem.  Why are you using the
imbedded CALLEE macro, these statements could be executed directly in the %DO
loop.
 
2.  The names of the parameters for the CALLER macro are longer than 8
characters.  This may be why you're getting the non integer error message? Just
use FROM and TO.
 
3.  I assume you're trying to pass the value of the %DO loop index variable to
the CALLEE macro, it should be &k, not %k.
