Re: st: RE: forvalues gives "numlist has too many elements" error
Problem solved. It was not as I explained it at first. The problem was
with foreach. When I replaced it by forval, I still got the same message
error, but it was
because there was another foreach further down in the code, which I had
forgotten about.
Thanks much Nick for pointing me towards what the real problem was (and
for the suggestion re nullmat).

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?

The code below worked fine, until I tried it with `1'==10000
(`1' refers
to the number of repetitions in a simulation).
When I did this, I received the following error message:
"invalid numlist has too many elements
r(123);"
The help info on r(123) didn't help me -- it refers you to [U] 11.1.8
numlist, but I didn't find anything
useful for my problem there.
Any thoughts? Is there a workaround this issue?

mat MR`posed'=(MR`posed' \ mr`posed'_`rep')
