Re: st: Limit of numlist

[Nick Winter <nw53@cornell.edu>]

This doesn't speak to the numlist limit question, but your code could 
simply use -forvalues- rather than -foreach ... numlist-.

There is no reason to have Stata create and store the numlist, rather 
than simply iterate through the values from 1 to N.

Your code could be:

forvalues i = 1/`l' {
        ...
}

Or even better,

forvalues i = 1/`=_N' {
        ...
}

That is, you can skip the -count- and just have Stata evaluate the 
macro expression `=_N'.
