[plt-scheme] Counter

From: Todd Dobmeyer (dobmeyer.2 at wright.edu)

I am working on a loop that uses a counter. I want to compare the counter to
the length of the string. I saw somewhere they used:

 

(number=? counter string-length str)

 

But my DrScheme says I cannot do this. Do I need to require some library or
what? Thanks!
