Code:
;Example 1
//while ($read(names.txt, nw, *Fred*, $calc($readn + 1))) echo -a $v1

;Example 2
var %dude = Fred
//while ($read(names.txt, nw, *%dude*, $calc($readn + 1))) echo -a $v1


Example 1 works without a problem. I'll pull the string that starts with Fred. But example 2 doesn't do anything. Is it possible to do a search with a variable?

I've been googling for ages and can't figure it out. I'm not exactly the best at this kind of stuff.
