Actually, the %EOF and %ERROR bifs are working fine as coded.  It seems that
RPG recognizes them as Boolean.  I believe that the IF statement recognizes
'0' and 0 as false.

The solution was to encapsulate the %SubSt call in parenthesis ( ).

%EOF and %ERROR, as BIF's, returns "0" or "1"...

              DoW ( NOT %EOF(Source) ) AND ( NOT %Error ) AND
                    ( NOT %SubSt( %TrimL(ThisLine): 1: 2) = '/*' );
RNF7421S Operands are not compatible with the type of operator.

The %SubSt is highlighted as the error.  What is wrong with this code?

I changed %TrimL(ThisLine): to 'XXX': to test, and same error.

Is RPG trying to do an assignment instead of a comparison?  What am I doing
wrong?
