; PROCEDURE PrintScramble()
;
; This procedure writes a string with a random scramble effect
;
; Warning : This procedure NEEDS to find spaces where the string will be
; printed... if not, a endless loop will occur...
; To ensure that everything is ok, you should add a CLS before or someting
; like :
; Print Space(len(Str))
; Backup len(Str)
