comments in lex

[Ray Reeves]

I'm new to lex, and the first thing I tried wouldn't fly!
How do you recognise a PL/1 style comment?
This is what I did:

startcom	\/\*
endcom		\*\/
%%
{startcom}[^{endcom}]{endcom}	printf("%s","comment")

But negation doesn't take conjunctions, even when packaged like this.
What should I do?
