The match values may be single characters or strings, or a mix of both. The match values are searched for, in order of appearance in the code, at each position in the source string. Inspection starts at the leftmost character of the source data item and proceeds, character by character, to the rightmost character. The first value in the match set is "cd". The first element, "c", is compared to the value "a" for a match. No match. The second value in the match set is "e". The third value in the match set is "f". There are no untested values remaining in the match set. The current position in the source data item is advanced one position to the right. The sequential testing of the members of the match set to the value of the current position in the source data item is repeated. None matches. The first match value is "cd".
