" perhaps the %03s was the problem and when changed to "%03.0f" did it"
See -help f_string- which talks about "numeric display format":
string(n,s)
Domain n: -8e+307 to 8e+307 and missing
Domain s: strings containing %fmt numeric display format
-tostring- is a wrapper for -string()- so the same insights apply there.

I am exporting to a text file, and while the zeros were appearing in
the stata data editor, each time I used outsheet, the leading zeros
were dropped
perhaps the %03s was the problem and when changed to "%03.0f" did it
*****
bysort plot: gen bldg=string(_n, "%03.0f")
*****
works like a charm
thanks Martin!
