awk from end of string -3 position comparison

Hi, I would like to check if the 3rd character from the end of a string is a d or p using awk and the field seperator would not help for this problem, i.e.

Code:

zgcdedgh

zgcdepgh

zgcdeigh

Any tips would be appreciated.

Why not use a regular expression like /d..$/ or /p..$/ ?
