Bug: String(n, str) on fw3 [fix: documented as feature]

String (n as Integer, str as String) as String does not perform as expected on firmware 3.
Cue the doco example:

BrightScript Debugger> print String(4,"ab") ' prints: abababab
aaaa

Creates platform fragmentation: code using string() will get different results on fw3 and fw5.
