Hi All; I would like to match a string if it has only cero or more of a defined set of characters. For example: if "GACT" are the characters, then
GACTNGACT ## This string should not be matched because it has the extra character N GACCCCCCC ## This could be matched; Any help to solve this problem will be greatly appreciated. cheers ******************************************************************* PEDRO A.
