In what language? Applescript? Shell? awk? perl? Other?

Code:
$ echo "J1705PEAN038TDMN" | grep -o "[0-9][0-9][0-9][^0-9]*$"

038TDMN

$ VAL=$(echo "J1705PEAN038TDMN" | grep -o "[0-9][0-9][0-9][^0-9]*$")
$ VAL=${VAL:3}
$ echo $VAL

TDMN

$

There's probably more elegant ways depending on what your string actually comes from. You could probably extract it - or several - from a file and whittle it down to TDMN, etc in one step.

am parsing a tab delimited text file, one line at the time, your solution works fine, thank you for your help!

Your solution will be very inefficient doing it this way. Care to show your code so I can build it in rather than calling a pointless external? It's quite possible the entire file can be handled in one awk call, instead of having to call grep over and over and over..

is it always the LAST non-numeric sequence of a string?
