st: Re: 'Transposing' data- follow up question

["Michael Blasnik" <michael.blasnik@verizon.net>]

If the data are in order by region within company, then you can just 
generate the region variable as:

bysort company: gen int region=_n

But if there are missing regions in the middle of the data for a company, 
then Stata would need ESP to determine which observations correspond to 
which regions.  I don't think ESP will be available until Stata 11 :)
