If you are getting a type mismatch error, you must be using Stata 7 or
earlier (Stata 8 will generate a string as needed). You would need to type
:
g str15 newid=trim(caseid)
except this won't do what you want since trim will only trim from the
beginning and end, not the middle. You need to use subinstr:
gen str15 newid=subinstr(caseid," ","",.)
would eliminate all single spaces within the text.
