'Viola ! Now here's a real beaut . Took a lot of my time, but it works real
'well ! There might be a few bugs ( tho me not find one ) and I would really
'appreciate it if you point 'em out me so that I could fix 'em .
'I had to steal a few subroutines from previous ABCs and being the Mr.Nice
'that I undoubtably am, I think I'll give these chaps some credit .
'Many thanx to :---
'1) Chris Wagner ( mouse subroutine ; the best I could find )
'2) Erik Olson   ( Edit Box subroutine ; real neat function )
'Keep up the good work guys and I'll always come up with an application !
'I was going to include a custom setup utility . I had already started making
'a subroutine . That I didn't find it challenging enough to get my grey cells
'ticking is a different story altogether ! . So u programming tyros out there
'vying to get ur names on the ABC, go ahead n' complete it if you want .
'And u programming gurus out there, tell me if you make any changes and do
'ask me before ripping it apart .


'Coming Attraction :
'Watch out for WARSHIP I : A superb(?) space game with real neat
'                          grafix n' sound ( varooom! varooom!! )
