How to put old binary data file from DOS in spin?

Good question for the 8-bit CPU emulator programmers:

I tried something like this, wondering if my biggest problem would be finding the data.
(as in, would "stuff" have the value of the address of the first byte?)

OBJ
stuff = "stuff.bin"

But I got an "unknown character error in stuff.bin" message.

Nothing else is obvious as a potential "INCLUDE".

It would seem silly to write a QBASIC program that generates a DAT section with a lookup table of longs from it,
and cut and paste that into my program like that.
How do you guys do it "the EASY way" especially if you don't have a DOS machine?

How do I get the binary data from the file into the hubram or eeprom and find the first byte of it with my spin program?

    Put it into a "file" statement in a DAT section.

    This is how I get a Z80 boot ROM image from a file:

    DAT
    rom_z80       file "ZIBOOT.COM"



    The you can read the bytes in Spin

        firstbyte := BYTE[noparse][[/noparse]@rom_z80]

    otherbyte := BYTE[noparse][[/noparse]@rom_z80 + someoffset]

    For me, the past is not over yet.

    OH! Ok thanks. I would never have thought of DAT ... label file "filename"
    Never saw it before and probably wouldn't unless I read all your source code.

    I'd love to hear more about this project your working on, based on what you are doing it sounds interesting..

    BTW, What OS are you using to run QBASIC? Being a 16bit application it always has the tendency
    to push the CPU speed to a solid 100% making it unusable under XP. Did you find a way around
    this issue?

    Fwiw, we have several legacy apps with similar issues (including Quick Basic), and they run fine·in a Win98 MS virtual pc envirnment.· Vpc is free from MS, but you will need a license for installing 98.

    What happens if you run some version of Windows in a virtual machine under XP and run QBASIC and such there?

    From time to time I use VirtualBox from Sun. Its free. Very easy to set up and use.

    While running an emulated 95/98 is fine, I prefer an easier and more lightweight approach- running apps like that in DOSBox when on another x86 machine, or within a real DOS image in an emulator like qemu.
