No wildcards required since string variables can be used in ranges:
tab codes if codes>="O140" and codes<="O150"
or
tab codes if inrange(codes,"O140","O150")

>Hello friends of the stata list. I have a database with 4 digits codes, for
>example: O140 where the first character is a letter. Those codes are strings
>and I want to know how to tabulate frequencies of some codes using
>wildcards. For example I want to get the total number of codes who are
>between 0140 and 0150, what can I do?
>Thanks
