Dear Allin,
Something weird is still going on there. It worked absolutely fine
before !!!!!
After the above performance of your script (below), I moved back to
1.014 seconds for only 10 000 obs and to more than 22 seconds for a 50
000 obs dataset ?!?!
set echo off
set messages off
nulldata 10000
series x = normal()
matrix m = zeros($nobs,1)
set stopwatch
loop for i = 1..$nobs --quiet
m[i,1] = x[i]
endloop
printf "elapsed: %g seconds\n", $stopwatch
