I searched the group but haven't found any message linked to this
issue.


I tried to generate code for a small file using lex, but got the
following error :


210: (Error) Definitions too long


I tried to shorten the length of each name definition, but it doesn't
work, and sometimes I got


209: (Error) Definitions too long


removing several name definitions from the definition part may solve
the problem, but it cannot be my option, anyway to fix this problem?


Furthermore, I failed to get the version of this lex utility, it
doesn't recognize any option except for
-t, it should be an AT&T version I guess.


Your comment are highly appreciated.
[I can't ever recall seeing that message. My usual advice to people trying
to use AT&T lex is to switch to flex. It's freeware, it's not a big
package, it's really easy to install. -John]
