So I was wondering what commands you guys could think of that you wish were present in TI-83+/84+ BASIC?

Or what commands do you with were on all of the OSes? For example, remainder() and RandIntNoRep() is pretty cool, but I prefer OS 2.43 which does not have those. So I will start a list:

1) remainder()

2) RanIntNoRep()

3) SubList() (to retrieve portions of a list)

4) SubMatrix() (to retrieve a portion of a matrix)

5) →prgmNAME(Line#) to store a string to a given line number in a BASIC program

6) modexp() to return the remainder after raising a number to a power.

7) inverse() to return the inverse of a number in a given mod system.

8) IsPrime()

9) NextPrime()

10) PixelCircle() to quickly draw a circle (in assembly, it can be done hundreds of times per second)

11) PixelLine()

12) str() to convert a number, list, or matrix to a string

Add more!
