But that seems inconsistent with what happens.
The udf is simply
function pad(st,stle){
if(len(st) GE stle) return left(st,stle);
st=st & repeatstring(" ",stle-len(st));
return st;
}
If st were a pointer to an array wouldnt the udf choke?
In fact the udf functions as designed, it takes the column value and pads is
appropriaately
