Just finished one (don't ask me to show it - very clumpsy Python code - still in learning mode). :) Here's one for parsing integer: # b 0 1-9 , . + - ' " a-Z \n # S0: S0 S0 S1 T0 E S2 S2 E E E T0 # S1: S3 S1 S1 T1 E E E E E E T1 # S2: E S2 S1 E E E E E E E E # S3: S3 T2 T2 T1 T2 T2 T2 T2 T2 T2 T1 T0: you got a null token T1: you got a good token, separator was "," T2: you got a good token b, separator was " " E: bad token > :) > Andrew > [EMAIL PROTECTED] > -- http://mail.python.org/mailman/listinfo/python-list
