a mistake that newbies usually make is to say some thing like: 1 -> Mat A[1,1]

when actually, you need to do this first to prevent a mem error: [[0][0]] -> Mat A

That creates a matrix. 1-> Mat A[1,1] does not create a matrix, so if it doesn't exist, you get a mem error.

Just thought i'd add that info, since a lot of BASIC progs have that problem.

There are other ways to create a matrix other than [[0][0]] -> Mat A, however, I have not programmed casio for 2 years and have forgotten. Something like Dim Mat A, or setting the number of rows and columns

You are right, the syntax is {<rows>,<columns>} -> Dim Mat A.
It's also worth noting that the closing brackets at the end are optional (e.g [[0][0->Mat A). It looks messier but it saves space.

I know there are ways to check for particular values in a matrix:
And display certain characters as a result:
Eg: a 5 x 5 matrix

Code: [Select]

[[5][5]]->Mat A
[[1,2,3,1,2][2,3,1,2,1][3,1,2,1,2][1,2,1,2,3][2,1,2,3,1]]->Mat A
For 1->A To 5
For 1->B To 5
Mat A[A,B] = 1 => Locate B,A, "O"
Mat A[A,B] = 2 => Locate B,A, "M"
Mat A[A,B] = 3 => Locate B,A, "N"
Next
Next

Try and see what that says

So has anyone figured out a way to have dynamic coloring? I mean for example if I got the code:

Code: [Select]

For 1->A To 10
Red Locate 1,1,"HELLO WORLD!"
Red Locate 1,2,"THIS IS A TEST"
Red Locate 1,3,"PROGRAM!"
Red Locate 1,4,"BUT IT TAKES"
Red Locate 1,5,"WAY TOO MUCH"
Red Locate 1,6,"BLEEPING SPACE"
Red Locate 1,7,"OPTIMIZE PLZ!"
Magenta Locate 1,1,"HELLO WORLD!"
Magenta Locate 1,2,"THIS IS A TEST"
Magenta Locate 1,3,"PROGRAM!"
Magenta Locate 1,4,"BUT IT TAKES"
Magenta Locate 1,5,"WAY TOO MUCH"
Magenta Locate 1,6,"BLEEPING SPACE"
Magenta Locate 1,7,"OPTIMIZE PLZ!"
Blue Locate 1,1,"HELLO WORLD!"
Blue Locate 1,2,"THIS IS A TEST"
Blue Locate 1,3,"PROGRAM!"
Blue Locate 1,4,"BUT IT TAKES"
Blue Locate 1,5,"WAY TOO MUCH"
Blue Locate 1,6,"BLEEPING SPACE"
Blue Locate 1,7,"OPTIMIZE PLZ!"
Cyan Locate 1,1,"HELLO WORLD!"
Cyan Locate 1,2,"THIS IS A TEST"
Cyan Locate 1,3,"PROGRAM!"
Cyan Locate 1,4,"BUT IT TAKES"
Cyan Locate 1,5,"WAY TOO MUCH"
Cyan Locate 1,6,"BLEEPING SPACE"
Cyan Locate 1,7,"OPTIMIZE PLZ!"
Green Locate 1,1,"HELLO WORLD!"
Green Locate 1,2,"THIS IS A TEST"
Green Locate 1,3,"PROGRAM!"
Green Locate 1,4,"BUT IT TAKES"
Green Locate 1,5,"WAY TOO MUCH"
Green Locate 1,6,"BLEEPING SPACE"
Green Locate 1,7,"OPTIMIZE PLZ!"
Yellow Locate 1,1,"HELLO WORLD!"
Yellow Locate 1,2,"THIS IS A TEST"
Yellow Locate 1,3,"PROGRAM!"
Yellow Locate 1,4,"BUT IT TAKES"
Yellow Locate 1,5,"WAY TOO MUCH"
Yellow Locate 1,6,"BLEEPING SPACE"
Yellow Locate 1,7,"OPTIMIZE PLZ!"
Next

Pretty repetitive, right?

Well I wonder if I can simply have something like the following pseudo code?

Code: [Select]

For 1->A To 10
For 1->B To 6
If B=1
Then
<code to set color to Red>
EndIf
If B=2
Then
<code to set color to Magenta>
EndIf
If B=3
Then
<code to set color to Blue>
EndIf
If B=4
Then
<code to set color to Cyan>
EndIf
If B=5
Then
<code to set color to Green>
EndIf
If B=6
Then
<code to set color to Yellow>
EndIf
<color set> Locate 1,1,"HELLO WORLD!"
<color set> Locate 1,2,"THIS IS A TEST"
<color set> Locate 1,3,"PROGRAM!"
<color set> Locate 1,4,"BUT IT TAKES"
<color set> Locate 1,5,"WAY TOO MUCH"
<color set> Locate 1,6,"BLEEPING SPACE"
<color set> Locate 1,7,"OPTIMIZE PLZ!"
Next
Next

I forgot if we need the Then/EndIf when there's only one command to execute, since it has been so long since I last coded in Casio BASIC, but you get the idea. It might also be very helpful for tilemap generation.

fxdev · « **Reply #110 on:** October 26, 2011, 09:36:50 am »

Here's my solution (Replace '_' by ' '):

Code: [Select]

"HELLO WORLD!________
_THIS IS A TEST______
_PROGRAM!____________
_BUT IT TAKES________
_WAY TOO MUCH________
_BLEEPING SPACE._____
_OPTIMIZE PLZ!_______
_"->Str 1
ClrText:0->I
Do:I+1->I:I>7=>1->I
For 1->J To 7
I=1=>Black Locate 1,J,Str 1
I=2=>Blue Locate 1,J,Str 1
I=3=>Red Locate 1,J,Str 1
I=4=>Magenta Locate 1,J,Str 1
I=5=>Green Locate 1,J,Str 1
I=6=>Cyan Locate 1,J,Str 1
I=7=>Yellow Locate 1,J,Str 1
StrRotate(Str 1,21)->Str 1
Next
LpWhile Getkey=/=47
ClrText:" "

Wait I thought Locate had no word-wrapping?

EDIT Actually nvm I didn't notice the sub-string command stuff.

EDIT That works, thanks

EDIT THat string rotate command is just cool!

z80man · « **Reply #112 on:** October 27, 2011, 12:58:37 am »

I like how casio BASIC has all those string based functions similar to the high level ones found in languages such as C. I find them useful for heavily text based programs such simple CAS's and other math/science programs.

DJ Omnimaga · « **Reply #113 on:** October 27, 2011, 01:24:19 am »

If it wasn't for the fact Locate lacks word-wrap, some of them could be very handy for scrolling.

I've been attempting to make a 'protected' program. I want people to be able to run it at any time but I want to prevent them from transferring the program(s) to other calculators. Unfortunately the built-in password function of the fx-9860 GII only prevents one from editing the program, not from transferring it. I've been trying to think of ways to make sure people can't transfer the program to others but so far to no avail.

The problem with an idea such as a password built in the program I modify for each person I give the program to is that the password will just be copied along with the program. Does anybody know a solution to this problem or whether or not there even is one?

Eiyeron · « **Reply #115 on:** December 08, 2011, 11:04:07 am »

Nope, sorry. i dunno how I could block a program. Send a backup will you send the totality of your ram, and thus what that's let's the program start.

You could with C progs, but for basic, i Think no.

z80man · « **Reply #116 on:** December 10, 2011, 02:39:05 am »

Unless you could call a C lib from a basic program then no. Such lib would need someway to individually identify the calculator it runs on such as for example checking a unique hardware id

sjasogun1 · « **Reply #117 on:** January 18, 2012, 07:46:55 am »

In the guide of the Casio fx-9860 GII I found a list of data items that can be sent over communications. In regards to my previous question a data type that is missing from this list could be used to contain a unique password of sorts. The problem is that I haven't found any data types not present on this list. But since there is a list in the first place I am sure they must exist. Do any of you see a data item missing from this list?

Spoiler For Spoiler:

Original data can be found through the link down here, page 318 and 319.

Everytime I try to use LOCATE 1,1, "test" I never am able to. It always says "Syntax Error".

I upgraded my FX-9750GII to the FX-9860GII operating system, is this a possible reason that LOCATE always gives a syntax error?

DJ Omnimaga · « **Reply #119 on:** August 22, 2013, 01:00:08 am »

Make sure there's no space between Locate 1,1, and "text". However I didn't code in Casio Basic for a year so I might not remember the real syntax well anymore. Anyway also make sure to select Locate from program commands, not type it letter by letter.
