Autzoo.1596 net.bugs.v7 utzoo!henry Thu Apr 22 20:47:40 1982 lex bugs The following are locally-discovered bugs in lex:

1. The minimal lex program, "%%", which supposedly copies input to output, in fact exits immediately.

2. Lex is weak on syntax checking. In particular, a null action does strange things and is not diagnosed. The example in the Bell manual page contains a null action that should be a semicolon.

3. Ratfor output has been essentially abandoned, as is documented in the machine-readable lex manual but *not* in the printed V7 manual.

4. The lex library, which should be named libl.a, is in fact named libln.a . Its sources are in the lex source directory, and the makefile there builds it properly.
