Subject:      inserting (not replacing!) characters into strings

I have eight digit (character format) patient IDs ("PT") (ex: 28300102)
that I need to insert hyphens into to give me 28-32-0102. I tried the
substr function (for the first hyphen only) [substr (PT, 3, 1) = "-";], but
this will replace the original value with a "-" rather than inserting the
hyphen (i.e., it gives "28-00102" instead of "28-300102"). Any help would
be greatly appreciated! Hope this was clear.
