Getting started in Casio-Basic? You can ask here.

[flyingfisch]

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.

[Jonius7]

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.

[Jonius7]

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 All | Copy To Clipboard

1 2 3 4 5 6 7 8 9 10

[[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 All | Copy To Clipboard

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44

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 All | Copy To Clipboard

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35

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.

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

Code: Select All | Copy To Clipboard

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23

"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]

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]

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]

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]

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]

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 Hidden:
