Anderson, ›        (Reprinted with THANKS!)››     Here are some tidbits for 8-bit›Atarians (tested under DOS 2.0): To›determine which revision of Atari BASIC›you have, type PRINT PEEK (43234).  If›the result is 162, you have revision A;›if it is 96, you have revision B; if it›234, you have revision C.››Need to format a disk from BASIC?›You don't have to back out all the way›to DOS. Do it with a one-line BASIC›program: 1 XIO 254,#1,0,0, "D:"  Load›this program and then don't forget to›put in a new disk before you run it!  ››Want to format a disk in the direct›mode? ›Try typing X=USR(3352). Have two files ›on disk with the same filename?  This›can be a nasty occurance, but there is›a way around it: Copy the loadable›(first) file to another disk as a›backup.  From BASIC, type POKE 3118,0›<RETURN>.  Go to DOS, and rename the›file (only the first file will be›renamed).  Go back to BASIC and type›POKE 3118,184 <RETURN>.  You should›now be able to access both disk files›on your original disk.››Want to disable the <BREAK> key in›your programs?›Insert the following after every›GRAPHICS command: POKE 16,64:POKE›53774,112.  Remember, once is not›enough with this one.  You've›got to keep disabling the <BREAK> key›after each of the commands listed›above.››Want to disable the entire keyboard?›POKE 16,255 will do that for you.››Want to create a run-only file?›Give this one a try: 32767 POKE›PEEK(138)+256*PEEK(139)+2,0:SAVE›"D:FILENAME.EXT":NEW.  Insert this›line into your program (make sure you›save a normal version of the program›first), and then type GOTO 32767›<RETURN>.  The resulting file can be›run normally, but not listed.››Need a random number between 0 and 255?›Sneak a PEEK at memory location 53770.››Want to create a MEMSAVE file from›BASIC so you don't lose your program›when you go to DOS?›All you need to do is type A=USR(5947) <RETURN>. ››(Owners of XL/XE series computers will›need to hit <RESET> after the disk›stops spinning.)›               ››  <><><><><><><><><><><><><><><><><>›
