Hi, I'm trying to do a substitution and am having trouble in that I am getting non-specific matches...I'd like to specify the regular expression to match any character to the left of $code and nothing or the end of the array element on the right of $code...is there a character class or some other way to specify the end of the array element?

thanks,

For an array @TREE, the gist of the substitution is this

       #if ($TREE[$n] =~ m/(.*)$code/) {print "MATCH"." ".$code."VALUE->".$id_global{$code}."<-\n";}else {print 
"NO MATCH"   ." ".$code."<-\n";} #works,matches all values w/right val
   $TREE[$n] =~ s/(.*)$code/$1$id_global{$code}/; #Yea!...now it substitutes 
one value correctly
   }
   #print $TREE[$n].":"."\n";
   $n++;
   $count++;
 }
}
print $TREE[$n].":";

You probably want non-greedy matching, e.g.

m/(.*?)$code/
