This is my first post, so apologies if this is the wrong forum.
 I am trying to learn Regular Expressions using the book written by Andrew Watt.

I can get the following expression to work:

ie find any line that starts with "43C" and 3 hex characters

regex_match(left(Varline,6),"43C[0-9a-f]{3}","I")

ie processing the first 6 characters of variable Varline

But when I try to get the expression look for any matches anywhere in Varline, it fails, this is what I coded?

regex_match(Varline,"43C[0-9a-f]{3}","i")

so I stuck, any help welcomed
