I can't reproduce this as a problem with -forval-. 

Much of the point of -forval- is that it doesn't 
construct a numlist. (By the way, it will not accept 
numlists in general.) If it did, there would be 
no rationale for it as a separate command. Rather, 
it constructs its counter on the fly, so enabling 
speed and storage gains over the equivalent -foreach-. 

On a separate detail, using -nullmat()- would enable
you to remove the -if/else- branch. 

How are you assigning to local macro 1?
