Hi,

I would like to extract a section of text from a list of drawing numbers.

For example ....

LEFT\ADV CONT\S3JL081P0251 REV D.DWG

LEFT\ADV CONT\S3JL081P0252 REV E.DWG

LEFT\ADV CONT\S3JL081P0253 REV D.DWG

LEFT\ADV CONT\S4JL081P0254 REV E.DWG

LEFT\ADV CONT\S4JL081P0255 REV F.DWG

LEFT\ADV CONT\S4JL081P0256 REV F.DWG



The part I want to extract is anything inclusive from "S3" or "S4" to the
end of the text string but not including the ".dwg" part

Please could someone help me with a function string to do this ?

Thankyou
