BAM: SCROLL statement "super-test"

[CharlieJV]

If you feel like beating the thing up: test version of BASIC Anywhere Machine.

The test program:

• Run the program
  
• View the source code
  

EDIT:  The program loops through various scrolling scenarios, incrementing the number of pixels scrolled by 1 every iteration of the loop.  Each scroll scenario performs the scroll 20 times.  All in fairly slow speed to give an opportunity to see positions of a pixel before and after a scroll statement.
