What does this program mean? it doesn't make any sense to me! how am i supposed to type it into my calculator?

\Abs (\Mat A[A,B])=1\=>\GotoA

[Bob Vila]

i think that it might mean

Abs (Mat A[A,B])=1=>Goto A [EXE]

guys correct me if i am wrong

again the \ infront of text represents a command and not plain text. there was just a post about this
hopefully quick questions like this can be answered better/faster once the irc chan get's up and running

[betoe]

Is someone in the #ucn-chat right now? when i sing-up to that channel, i'm the only user , or thats not the correct name?

[ross8653]

me and crimsoncasio are in it now you must be on a different network make sure you connect to a dalnet server

i understand what \ means, what confuses me is what the expression actually means?

take absoluate value of matrix A[A,B], then what? what is '=a=>GoTo A'?

[CrimsonCasio]

do you have a CFX modle calc? if so then hit Shift' /> VARS' />F3' />F3 that is the => arrow. it means (if) Abs (Mat A[A,B])=1 (then) Goto A

or in english: if the absolute value of matrix A at cell coordinates A,B is equal to 1 then Goto the lable A and resume execution from there.

my calculator is ALGEBRA FX2.0, i tried your way but i only got '?' symbol.

but if '=>' means 'then', can i use the 'then'command ?
Shift' /> VARS' /> F6' /> F1' /> 2' /> ? this command will give me 'then'

i download this program from www.casio-programs-avenue.com
it says this program can work on all graphical calculator, i am not sure if it can work on mine, since i have encountered quite lot of problems.

how do you express 'greater than and equal to' in the program? not '=>' ?

[betoe]

"how do you express 'greater than and equal to' in the program? "

In the program menu ( Shift' />+VARS' /> ) search the "logic" menu, choose and press 1. There will appear <,>.... symbols.

Yes, but you have to use full
If - Then [-Else] - IfEnd structure.

If you can connect to PC and you have Fa123 casio program then you can write there this implication symbol (i think you should write there '=>') which is not directly possible on AFX.

i tried your way, but it doesn't give me '=>'(then), symbol.

[betoe]

I tried that and crimson is right

When you are editing a program, choose the PRGM menu (with Shift' /> VARS' /> ), then press JUMP (with F3' /> ), and the => symbol will appear, available with the F3' /> button.

I see in your profile and you only have an AFX 2.0, the => symbol is not available in this calculator (in CFX as crimson say). You need to take this symbol from one CFX program, with the help of the FA-123 and a link cable.

[Overlord]

it's better to transfer the => command because :

- => is shorter than If Then IfEnd

- a GOTO command in a "loop" (If/For/Do/While) = AAARGH ! it's bad because the program won't reach the IfEnd/Next/LpWhile/WhileEnd so the loop will never end...

[huhn_m]

On the AFX the => Sign is not directly available. You have to copy an CFX program from a frien (F3 F4 F5 in Link menu to receive from CFX!) and copy & paste the => (using CTRL' /> + [->] / [CTRL + [COPY] / [CTRL + PASTE] to copy 'n paste)

[neo]

i don't have a cable to connect with computer, could u please tell me another way of doing this, thanks

[Overlord]

you can connect the AFX to another calc and then transmit a program with the => command

[CrimsonCasio]

or you could just use the If statement...

[neo]

is there anywhere i can find program that is designed for algebra fx 2.0? (except www.casi0-programs-avenue.com).

[Bob Vila]

i think casiocorner.com

[CrimsonCasio]

my site too (see below).

[neo]

got it!
