st: genhw error

["Tony Black" <tblack@u.washington.edu>]

I am having difficulty with the "genhw" command
With this simple dataset:

allele1	allele2
A		A
A		G
A		A
A		G
A		A
A		A

I issue the following command:

. genhw   allele1 allele2

and get this result (in red)

',' found where integer expected

I set trace on and it seems to be blowing up in "genhwi" -- here is a snip
from the trace file

  - genhwi `vars', `labopt' `binvar'
  = genhwi 4  2, label(AA  AG) 
 
----------------------------------------------------------------------------
------------------- begin genhwi ---
    - version 6
    - qui {
    - gettoken AA 0 : 0, parse(" ,")
    - gettoken Aa 0 : 0, parse(" ,")
    - gettoken aa 0 : 0, parse(" ,")
    - confirm integer number `AA'
    = confirm integer number 4
    - confirm integer number `Aa'
    = confirm integer number 2
    - confirm integer number `aa'
    = confirm integer number ,
',' found where integer expected
