You can always do a $len check on your string and divide that by the amount of chars per chunk you want and then base a while loop on it.

Code:
var %a = 6f1ed002ab5595859014ebf0951522d9, %b = $len(%a) \ 8, %c = My original result of %a as given me %b possible factors.
echo %c


Code:
if $reality > $fiction { set %sanity Sane }
Else { echo -a *voices* }
