Hello,

SUBJECT: Problem with error handling. 

I'm trying to write a lexer/parser that will read in a 
command line with switch options. 

Something like: cmdx -sw1 cbn kjy -sw2 mm -sw3 

In the lexer, I identify the switches (starting with 
hyphens) as tokens: SW_1, SW_2, SW_3 and the commands are 
identified as tokens too: CMD1, CMD2, ... and I identify the
non-switches as a parameter PARAM.
