Add functions to Basic Casio programs

[SimonLothar]

Yes, but where can I get the compiled code ?

I do not know, which SDK you use. With CASIO SDK you have to use SHC.EXE, OPTLNK.EXE and possibly ASMSH.EXE separately.
You have to ensure, that the BASIC-extension's entry-code supports the interface of int PRGM_Send( short*opcode, char**program, TBCDvalue result[2] ).

I can't redirect on this adress, only in changing opcode with syscall 0x0CB0 : int PRGM_Send( short*opcode, char**program, TBCDvalue result[2] ) ?

To redirect a syscall, the following steps have to be performed:
1. make a backup of your OS image
2. find the address of syscall 0x0CB0.
3. replace the bytes at this address with a far jump to the memory-address, which will contain the BASIC-extension-code (some fixed flash- or RAM-location; mind the alignment).
4. if the BASIC-extension should reside in the flash, copy the code into the target-address range (mind the limits), otherwise skip this step
5. adjust the checksum.
6. restore the OS image to your calculator
7. if the BASIC-extension should reside in RAM, use some G1A to load it into the RAM-range (mind the limits), otherwise skip this step
8. call PRGM_Send from out of a PRGM-program

Thanks a lot, I'm going to try:)

It's more difficult than I could imagine.

This is a small feedback :
1. done
2. I think I've found the syscall, see picture, but where is the offset ?
[ATTACH=CONFIG]46[/ATTACH]
3. I do not know how do this

7. I use Casio SDK. I have compiled my function and I will copy it at adress 0xA5600200. But how many bytes has a g1a file header ?

Hello all,

I have the PRGM 2 addin in my calculator.
I need some examples for the addin like reading the clock,displaying in smaller font size(like print mini) and some mathematical calculations.
How to create PRGM 2 files?
Please help friends.

Hi,

Thanks for try PRGM2, but it is not ready to use yet.
It's just a demo.

To answer your questions you should try examples that you can download here.
Sorry but currently the projet is only in french.

I'm going to work on it

Welcome Purobaz.

Its a nice program.
Kindly help me in creating programs for the addin.

Just write 'PRGM2 at the beginning of your program.
Then call a function like this :
function_number -> F
While F:WhileEnd

Currently you can't display a small font size easily.
You should wait a month. I will release a new version more understandable.

Wow a new version.
Go ahead all the best Purobaz.
Thanks for the help.

Sry. EDITs do not trigger notifications and tend to be missed. I will answer this afternoon.
