Flyguille When will a version be available that can execute programs? Anyway the Hello world demo can be seen? (other than in assembly that is)

Thanks by your interest... yeah, i are planning to release a second DEMO with aplications execution, and all the improvements than are already done.


Maybe before to the big remaking <---- That mean, i will do a big re-structuring of the ADR system (administrator of resources) <--- That mean, some functions to modify like TRUD functions, some useless functions deleted like DIV64 (for make free space), all the drivers and API will be fully remapped.

But the remapping are close to the current mapping, easy to re-write aplication code for fit with the new mapping.

That big re-structuring is needed for reach up to 255 drivers or libraries instead 16.

Some functions will be a bit faster and other a bit less faster.

Also is needed for improved the capabilities of the back-grounds process.

btw, did the compiled exec of hello world work?

You can't use the demo for test the HELLO world program... because is not too simply like renaming to MSXCOMMAND.EXEC and mount that on A: ... Why?

For do that, is needed to insert a lot of more code inside hello world aplicación...

Like:

. VDP initiation.
. mount CHRS design chart.
. ENABLE the KEYBOARD buffer.
. Create a window if you want, if not all PRINTING will go printed on the DESK.

Why VDP initiation?, because the kernel not do that... for allow to the user interface got the complete control of the view.

Mount chars design? .... YES, that chart aren't on kernel and need be mounted externally first.

Enable keyboard buffer? .... Yes, CON & PRN drivers are mounted externally on MSXCOMMAND.EXEC for allow to the User interface got the complete control of the printing on paper and console typing input.

By that reasons are not possible execute any aplication instead the normal MSXCOMMAND.EXEC user interface...

On other hand, the user interface are loaded and executed using a short load/run routine and not send all information on the CPU registers than some aplication will need.



Simply, wait for the second DEMO if you want test aplications programs.

I didn't mean that. You want to test it on MNBIOS yourself. I just want to know if it runs. That way I know the header system and the rest is correct.

I can't test yet, but i dump the compiled version in HEX and check the format and almost is correct.... also are correct the assembler code and the executing addresses on the header.

So, i think that work.

But , see the 000A0 position... got the value 00h.... that is a wasted byte.... i are bussy to check why... but allways it will run ok.

nop, is not a wasted byte, is the FlagTask variable

So, all ok.

I HOPE ThiS INFORMATION IS CLEAR

Ok, I understand now better. It still COULD be done like I suggested, but that would make initialize routine of interrupt handler quite a complex as you would need to make a table of addresses to call.

Long code for just saying "Hey babe, how you're doing" . ..

That is not a long code as it is multitasking assembler program. To compare... look here for Hello World program without BIOS:
