I cannot get a for next loop to print more than just the first variable. As in below:

$a="Joe"
$b="User"
for $cnt = 1 to 3
? $cnt + $A + $b
next

This is just an example. It seems to only print $cnt and ignores the additions. What I am doing is reading in the contents of a directory that has Ghost images and trying to create an indexed menu selection like:
1. Image1.gho
2. Image2.gho <---- trying to use the $cnt as selection no.
3. Image3.gho
What image to restore(1-3)?

So the line after the FOR I am using something like:
? $cnt + ". " + $file[$cnt}

Any idea's?
