st: re: problem with options

[Kit Baum <baum@bc.edu>]

Tiago has problems with options. The reason why MODEL is demanded is  
that he has not made it optional; Stata supports non-optional options.

. capture program drop rtpcr

. *! rtpcr v1. TVP 2007
. program define rtpcr, rclass
  1. version 9.2
  2. syntax varlist(min=2 max=100 default=none numeric) [if] [in] ,  
[MODEL(string)]
  3. di "`varlist'"
  4. di "`model'"
  5. end


. rtpcr pop gdp
pop gdp


. rtpcr pop gdp,model(junk)
pop gdp
junk

.

Works fine in both instances.
