abbreviations allowed in options of a user-written command?

[Lucas Mation]

Is it possible to write user-written commands that will accept abreviatoins in the options?

For example, syntax bellow works on both cases a nd th e help file for "merge" ndicates this by underlying the first 3 letters on the "generate" option.

  
merge 1:1 var1 using dataset, generate(var2)
merge 1:1 var1 using dataset, gen(var2)
 

How do I replicate this for a user-written command? For instance:

sysuse auto, clear
program test_prog
    set more off
    syntax varlist(min=2 max=2), generate(name)
    confirm new variable `generate'
    di "testing"
    gen `generate'=1
    end
test_prog weight length,  generate(c)    // works
test_prog weight length,  gen(c)          // does not work

Lucas,

Try:

 
syntax varlist(min=2 max=2), GENerate(name)

The upper case letters in the option indicate the minimal allowed abbreviation.

Regards,
Joe
