break up the number, then display the appropriate numbers. So it could look something like this:
load image "0.bmp",1
load image "1.bmp",2
load image "2.bmp",3
load image "3.bmp",4
load image "4.bmp",5
load image "5.bmp",6
load image "6.bmp",7
load image "7.bmp",8
load image "8.bmp",9
load image "9.bmp",10
thousands=mid$(str$(score),1)
hundreds=mid$(str$(score),2)
tens=mid$(str$(score),3)
ones=mid$(str$(score),4)
sprite 1,0,0,thousands+1
sprite 2,10,0,hundreds+1
etc etc
Basically, it just converts it into a string, and takes the character in each space (you may need to replace mid$() with left$(right$()), a way of doing the same thing, )without the problems of extra digits).
Hope this helps
Ever notice how in Microsoft word, the word "microsoft" is auto corrected to be "Microsoft" but "macintosh" just gets the dumb red underline?
