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.

See for example

program define testop

syntax varlist(min=2 numeric) [,option1 option2]
local nbitems : word count `varlist'

forvalues i=1/`nbitems' {
di "``i''"

.testop var1 var2 ,option1

.testop var1 var2, option1

.testop var1 var2,option1
