Many programming languages contain a StrReverse function to allow the 
programmer to quickly reverse the characters in a given string. This 
can be useful in creating passwords, games and for other things 
limited only the the imagination.

Here is a StrReverse clone in FB:

'~StrReverse Clone (reverses a string)

LOCAL FN StrReverse$( inputStr AS STR255 )
DIM AS STR255 revStr
DIM AS INTEGER i

revStr = ""
For i = 1 To inputStr[0]
revStr = revStr + LEFT$( RIGHT$( inputStr, i), 1)
NEXT i

END FN = revStr

DIM myStr AS STR255

myStr = " Hello, how are you?"

PRINT:Print "FN StrReverse$ reversed the letters this string:"
PRINT FN StrReverse$( myStr )
