Re: st: RE: programs with options

[David Kantor <dkantor@jhu.edu>]

To Jean-Benoit Hardouin:

You are referring to `1', `2', `3', etc., which are just the non-blank 
textual segments of the command line (after the command name).  Thus, the 
final one (`2' in your examples) may include the comma if there is no space 
after it in the command line.

These are not the same as the elements of the varlist -- until you 
-tokenize `varlist'-.

So one solution is to put
 tokenize `varlist'
into your program, before the `forvalues- statement.  But a better way to 
do this would be...

foreach var of local varlist {
 di "`var'"
}

(And you won't need `nbitems'.)

I hope this helps.
