Re: TIB: xyLine - fast, efficeint, few ppl know it



In a message dated 97-12-08 00:27:58 EST, you write:

<< P.S.. If you want to mess with someone's mind put this prog into their
calc.
 It is short and easy
 
 1/->/A
 Lbl 1
 If A=1:Then
 Goto 1
 
 This will give them a memory error in a min or less depending on how much
 free memory they have on their calc.  I Have no idea about the time it would
 take on an 86.>>


I like using jsut one line to do that:

:disp randM(255,255)

For some stupid reason, the calculator accepts this as a valid command, and
solves a random number for each elemnt of the matrix.  Since the calculator is
slow at finding random numbers, the effect will last a long time before the
calc gives you the memory error.  It is also good because you can't press [ON]
to break it!!!  The reason this fills the memory is well:  for EACH element in
the matrix, the calculator allocates one byte of memory...65025 bytes!  Since
the TI-86 has 96K of user mem, the disp command will tell the calculator to
temporarily store the matrix AGAIN into the Ans variable (the Ans variable is
controlled by the calculator as a temporary storage place, and so the user can
quicly recall the last result by pressing [2nd] [(-)])causing the memory to be
filled.  They will think that their calc is messed up!!
