Sasha,
I haven't looked at the rest of your code, only at the syntax
statement. Simply make this option -band(real)-. It is a compulsory
option, so you don't need a default value for it. The user is required
to enter a value for -band-. If you want to have it as an optional
option with a default value, change the line to
syntax varname using/ , dist(name) save(string) [ band(real 1000) ]
Hope this helps,
Eva
