In general, you will get better feedback if you include the output from
a program that isn't working, which will usually give clues about
*where* the program is breaking. That said, there are several things
here:
-- Don't capitalize the commands -- Stata is Case Sensitive.
-- No need to generate the time variable inside the loop; in fact, this
will crash on the second time through.
-- When referring to a local macro, be sure to distinguish the opening
and closing characters -- ` vs '
-- No need to define a program to loop. You can do this as:
set memory 32000
set matsize 800
use d:\all_variable.dta
foreach v of varlist v1-v100 {
lomodrs `v'
}
--Or you could do the loop with numbers rather than variables:
forval v=1/100 {
lomodrs var`v'
}
