st: RE: forvalues gives "numlist has too many elements" error

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?
