*+ Original version by René Straub 18-Jul-89 +*
*+ +*
*+ Modification History: +*
*+ -------------------- +*
*+ +*
*+ 23-Jul-89 CHW Created this file (99% rewritten :-) +*
*+ 08-Aug-89 CHW Zulange Textzeilen werden automatisch getrennt +*
*+ 06-Oct-89 CHW ShowMonoReq() hier hereingenommen +*
*+ 31-Oct-89 CHW ToUpper-Bug bei VANILLAKEY fixed +*
*+ 04-Nov-89 CHW ToUpper-Bug bei VANILLAKEY really fixed, Amiga-v/b +*
*+ 05-Nov-89 CHW No more gurus if word longer than 1 line +*
*+ 18-Jul-90 CHW itext->Font is now set for IntuiTextLength() +*
*+ 02-Nov-93 CHW Benutzt jetzt strlen statt StrLen (->Bobi) +*
*+ +*
***************************************************************************
** **
** Parameter : A0.L : Zeiger auf Text, Linien durch \n getrennt **
** A1.L : Zeiger auf PosText **
** A2.L : Zeiger auf NegText **
** D0.W : Bit 0: 1=Default PosText, 0=Default NegText **
** Bit 15: 1=Text hat Schatten, 0=normal **
** **
** Resultat : D0.L : 0=NegText angewählt, 1=PosText angewählt **
