I have a samll problem in awk (gawk specifically), and I hope this is
the right place for this posting (I couldn't find a comp.lang.awk,
maybe there should be one :-) ).

I have a datafile that looks like this

id	regex
PS0TEST	^MAQQWSLQRLA
PS1TEST	^M
PS2TEST	MAQQWSLQRLA$
PS00001	N[^P][ST][^P]
PS00002	SG[A-Z]G

I read this info into 2 arrays (id[], and regex[]).

All is fine up to this point.

then I want to loop through all the regexs and search each against 
a string

    if ($0 ~ /^M/) 
      printf("matches pattern '%s'\n", "test")

    for (i = 1; i <= regex_num ; i++ ) {
      if ($0 ~ regex[i]) {
	printf("matches pattern '%s'\n", id[i])
    }

So the first case works as is should (the pattern /^M/)
But the loop does not match anything. This appears to be
because the variable regex[i] is not being expanded
before the comparison, so every time $0 is being 
compared to the string regex[i].

Is there a work around for this. I can't seem to find any
mention of this sort of thing in "The AWK Programming Language".
