I'm looking to write a single interpreter that can simultaneously
parse up to 96 separate programs. Due to other restraints in the
program I cannot fork a process to handle each parser. What are my
options using lex and yacc? It seems like a real hack to get either
of them to handle more than one program.


Other issues I anticipate are per process limits of open file handles,
and general performance.


Can anyone offer any suggestions?


Thanks.
Mike
[I'd consider using a threads package. The context for a yacc parse isn't
all that hairy, so you might be able to package it up without too much
misery. -John]
