Or not even¢know your right poke from your left¢poke (pun intended)?¢¢Well maybe this article might help ¢most of our members (except for you ¢exceptional guys who know it all).¢¢For instance, did you know that to¢get out of BASIC if you forgot to¢hold down the option key when booting¢up with an XL or XE, you type:¢POKE 1016,1 [RETURN]..now press¢[RESET] and you will go to the DOS¢menu!¢ ***********¢¢That to determine which revision of ¢Basic you are using? Just type:¢PEEK(43234)¢¢If the screen shows:¢ 162 - You have Rev. A.¢ 96 - You have Rev. B.¢ 234 - You have Rev. C.¢(Rev. C is the best naturally)¢ ***********¢¢Do you turn off your computer every¢time you are re-booting? Why not give¢your micro a COLD START (without any¢booster cables too) just type:¢POKe 580,1 [RESET] ¢or¢A=USR(61733) which does same thing.¢ ***********¢¢Need a random number in the program¢you are masterminding? Just type:¢100 Print PEEK(53770)¢110 IF PEEK(53770)=173 THEN PRINT ¢¢¢"YOU ARE RIGHT!"¢ ***********¢¢Forgot to boot up a 'MEMSAV' file¢while in basic? No sweat, type:¢A=USR(5947)¢(NOTE, XL & XE owners press [RESET]¢when drive stops spinning!¢ ***********¢¢You also forgot to format a disk-and¢you have 400 lines of your newest &¢best program, RIGHT? Easy solution is¢to type:¢A=USR(3352)¢and you will format a disk in single¢density from BASIC¢ ***********¢¢Small innocent fingers tend to foul¢up your high score game while you¢weren't looking? Why not disable the¢KEYBOARD? Type in:¢POKE 16,255¢Press [RESET] to enable it again!¢ ***********¢¢ALTHOUGH I WAS GOING TO NOTE JUST¢PEEKS AND POKES, I THREW IN A COUPLE¢USR ROUTINES. NOW ALL I HOPE IS THAT¢THEY ALL WORK AS THEY ARE SUPPOSED¢TO. DONT BLAME ME IF THEY DON'T, I¢DISCLAIM ANY EXTRA ABILITY AT THIS¢COMPUTER STUFF!¢¢¢(IF SOME OF OUR MEMBERS, (or you the¢reader) SEND ME THEIR FAVORITE BASIC¢TIPS, we can spread them around, so¢drop me a note, wont you?)¢ ¢ ¢ =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=¢¢ Part 2¢¢ ALEX P.
