[Coco] NT: BASIC educate

[Glen VanDenBiggelaar]

Hi, all,
I thought I would ask a question about BASIC, that's been bugging me for 25 
years. Before I got my first CoCo (83) I learned BASIC on the old PET. one 
of the first things I discovered was that the "PRINT" statement could be 
substituted for just "?" (a question Mark). I then used this on many Apple 
2's, C64's, and ultimately on the CoCo.
My question is:
How come this is not documented anywhere in the Tandy Manuals, or in the 
many programs in Rainbow, etc? Is using this flaky? Is it just bad educate? 
or is it just to confusing for some? I know its just saving 3 keystrokes, 
but when you are typing in a 6 page program, it does save a bit of time.
