If -t- has been input, it is a non-empty string,

Or, more likely, I would fill in a default:
if "`t'" == "" local t "1 2 3"
Thus, the key is to exploit the fact that
such an option has no default and thus is
empty if and only if the user didn't specify it.

how do you refer to an option for a number list? for instance,
suppose I write an .ado file where t(numlist) is an OPTIONAL
element, so the user could input t(10
20 30 40 50) or no t at all. If I want to write a
case-selection statement that looks like:
if t has been input by the user {
...
}
else {
...
}
then what is the REAL code for the if-statement here?
