So it'd be something like

[:alnum:]{1,8} * (PARAM)|(TABLE)|(UPDATE)  { return TOKEN_BLAH; }

Or you could just use make your token returner into a subroutine and
call it from three separate flex triggers, as:

FIRSTPART [:alnum:]{1,8} *

{FIRSTPART}PARAM { return_mytok() }
{FIRSTPART}TABLE { return_mytok() }
{FIRSTPART}UPDATE { return_mytok() }
%%
int return_mytok()
{
	return TOKEN_BLAH;
}

Flex and bison are Way Cool. I did a project in 'em oncet just to play
with them. See <a  rel="nofollow" href="http://tomshiro.org/coldread/";>http://tomshiro.org/coldread/</a>

&gt;    I'm struggling with a pattern expression for lex. I'm looking
&gt; for an expression that handle an alphanumeric string of 1 to
&gt; 8 characters (only letters and numbers) followed by at least
&gt; one space and one of three keywords: &quot;PARAM&quot; &quot;TABLE&quot;
&gt; or &quot;UPDATE&quot;. I've tried several things with no success (I
&gt; won't post them due to embarassment). Anyone have any
&gt; suggestions?
&gt; 
&gt; Thanks!
