The RREF feature is probably not included in your calculator then,

The folded arrow pointing both left and right
The clock? type thing
Also, is the circular object at the end of every line simply saying "Start new line" as in press EXE?
Thanks very much, if anyone could offer a simplified version of this text or simply explain where i can find these symbols/objects as I make the program, that would be awesome.

For any other model the program must be typed in or transferred via cable, however the doc file given in the casioeducation link: http://www.casioeduc...A8-9088C88C19BF
needs to be viewed with the correct fonts.
I pasted the text from the rowreda.doc into the program Casform to find which font it is supposed to be (it turned out to be FA-121) and then converted it into plain text.
The plain text is:
"ROW REDUCE MATRIX A"
Dim Mat A
List Ans ->R
List Ans ->C
Mat A->Mat R
1->I
For 1->J To C
For 1->N To R-I
Mat R[I,J]=0=>Swap R,I,I+N
Next
If Mat R[I,J]<>0
Then *Row 1%Mat R[I,J],R,I
For 1->KTo R
K<>I=>*Row+ (-)Mat R[K,J],R,I,K
Next
Isz I
IfEnd
If I=R+1
Then Mat R[R,J]=1=>Break
Dsz I
IfEnd
Next
Mat R
(-) -the unitary negative sign
=> -implicaton symbol (if,then symbol)
-> -assignment arrow
<> -not equal to
% -represents the fraction symbol on the a b/c button
The location of the other commands is given in this table:

If this program doesn't work then there is another rowreda program in this topic:

I was thinking about the old 9x50 series models. Only the GB versions of the old 9x50 series have rref built-in.

For linear algebra, we need the RREF function on our calculators, and being the only one with a Casio fx-9750G PLUS (everyone else has TI-89 or Voyage 200s), I was worried I would have to shell out 120 bucks for a new calculator.
I input the program above and it works like a charm. Thanks again!!!!!

Hello. I am new here, and I have this fx9750g plus, and I need some advice about rref. first at all what kind of cable would i need for this? and some instruction on how to insert this program into my calculator?

You need FA-123 cable.
Concerning insertion, retype the program instructions to your calc.
The special characters and programming commands can be found after pressing shift+vars [prgm]
