Here is a way to make fasm APP's portable to most hobby OS.
Its called FBasic (Fasm Macro Basic), it use fasm macros to make a sort of basic language.
You just need to port the macros over to your OS functions.

Here is a GUI AND text mode example for DexOS.

This is a GUI example with background image:

This is a text mode example:
Image

Here is the source code to each:
GUI example with background:
Code:
include "BasicG\FBasic_G.inc"

FONT_SIZE 2
SCREEN 800 600 32
LOAD_IMAGE file_area_Menu, MenuBuffer
SPRITE 128, 2, MenuBuffer

COLOR  0x0057ffff
LOCATE 150,30
PRINT "This app is written in Macro Basic, for DexOS "
COLOR  0x00ff5757
LOCATE 150,50
PRINT "With the ease of Basic and the power of ASM "
COLOR  0x00ffffff
LOCATE 150,70
PRINT "It user's the basic commands:"
PRINT " "
PRINT "  CLS"
PRINT "  SCREEN"
PRINT "  COLOR"
PRINT "  LOCATE"
PRINT "  PRINT"
PRINT "  GOSUB"
PRINT "  RETURN"
PRINT "  SLEEP"
PRINT "  END"
PRINT " "
GOSUB TestSub
SYNC
SLEEP
END

TestSub:
PRINT "Press any key to quit."
RETURN


align 4
file_area_Menu:
file   'ScrMenu\ScrMenu.dif'
file_area_Menu_FileEnd:
rd 1
align 4
include 'Dex.inc'
align 4
VesaBufferTemp: rd 800*600
align 4
MenuBuffer:     rd 544*512+2
align 4
VesaBuffer:                           
    


text mode:
Code:
include "BasicC\FBasic_C.inc"

SCREEN 0
CLS
COLOR  11
LOCATE 2,1
PRINT "This app is written in Macro Basic, for DexOS "
COLOR  12
LOCATE 2,2
PRINT "With the ease of Basic and the power of ASM "
COLOR  15
LOCATE 2,3
PRINT "It user's the basic commands:"
PRINT " "
PRINT "    CLS"
PRINT "    SCREEN"
PRINT "    COLOR"
PRINT "    LOCATE"
PRINT "    PRINT"
PRINT "    GOSUB"
PRINT "    RETURN"
PRINT "    SLEEP"
PRINT "    END"
PRINT " "
GOSUB TestSub
SLEEP
END

TestSub:
PRINT "  Press any key to quit."
RETURN

include 'Dex.inc'

We will release the includes when more macro functions added (if you want them now let me know), as we are still changing things and need more macros added.

Just for fun, i coded a linux ver of the FBasic demos:

Image

Same code, just different include
Code:
include 'FBasic_L.inc'
CLS
COLOR  11
LOCATE 2,1
PRINT "This app is written in Macro Basic, for Linux "
COLOR  12
LOCATE 2,2
PRINT "With the ease of Basic and the power of ASM "
COLOR  15
LOCATE 2,3
PRINT "It user's the basic commands:"
PRINT " "
PRINT "    CLS"
PRINT "    SCREEN"
PRINT "    COLOR"
PRINT "    LOCATE"
PRINT "    PRINT"
PRINT "    GOSUB"
PRINT "    RETURN"
PRINT "    SLEEP"
PRINT "    END"
PRINT " "
GOSUB TestSub
SLEEP
END

TestSub:
PRINT "  Press any key to quit."
RETURN                                    
    

Let me know if anyone wants the linux include.

I can include these macros in FreshLib if you don't mind. It seems it will be easy to integrate them in the FreshLib structure. They can be used for debugging purposes and for quick sketching of console applications.
What about variables? Can I print for example value of eax register?

Cool, the DexOS ver "can print for example value of eax register", that Stephen did, i will convert it to the Linux include and post you link to the includes.

Stephen is working on add more command, so will be able to keep you up dated.

BTW, FreshLib is especially created to be portable. Do you think it can support DexOS?
It needs some low level and middle level functions to be supported by the OS:

1. dynamic memory allocations (heap).
2. Some basic graphics functions - lines and rectangles.
3. Basic windows functions - create, destroy, paint
4. file functions.

Yes, the only one i see a problem is 1. "dynamic memory allocations (heap).", as in DexOS the App its self is in charge of memory allocations, and can use all memory from app load address, to top of memory (top of memory is amount of ram on sys, usable by a 32bit sys, less any drivers loaded).

But there's ways around this, i could use the same method as used in the fasm port.

Here's the file for the FASM macro basic that ran on DexOS 3
The stuff after that is lost. I've started working on updating and adding stuff.

home.comcast.net/~dex-os/FBasDx01.zip

It probably isn't going to work in DexOS 6 (pointers got renamed and a few are gone), but is what I'm cleaning up and taking off from. So it's a bit useless other then to look at.
