Question : Parsing a Pattern from a String

Good Evening Experts.
I need help with parsing a string pattern from a variable length (memo).   I have many records, each with a memo fileld, which may contain an identifier in a predefined format.  The set of characters I need to parse out of the memo is 11 in length.  The first character must be E or P, the next 8 are alpha/numeric and the final 2 must be numeric.
