After reading in lines with readline() or readlines(), use 
string.splitfields(line,',') to split each line (this assumes that you do not 
have ,s embedded within quoted strings -- which is why people sometimes use 
something obscure like '|' as a field separator).  Then use == comparison or 
one of the string search functions to test f1.
