You could make the list`s remote debugging efforts easier by -set trace on- and reporting the area around the error...

Subject: st: Basic ado question

I am trying to convert a called do file to an ado with little success.
Besides inserting the program line at the top and end line at the
bottom, I have made no changes to the working called do version which
is executed with a number of arguments passed from the calling
program.  The error I keep getting is

variable NewCompanyNum not found
(error occurred while loading CalledPooledModel.ado)

without pasting the entire program here, the variable NewCompanyNum is
created within the ado itself with the following steps:

*Create contiguous variable
egen NewCompanyNum = group(CompanyNum)
summ NewCompanyNum
local Count = r(max)
dis `Count'

where CompanyNum is a numeric variable assigned to the starting
company data well upstream of this program.  Is there some restriction
on creating a new variable in an ado?  Do all the variables it uses
have to exist prior to its execution?  Thanks for any suggestion
anyone might have.
