Title: how to load data at end of program
Post by: MajorDill on October 06, 2016, 03:10:04 AM

I want to load another program at the end of my currently executing program then jump into that.   It would seem to be rather easy to 'db' a byte at the end of the first program and dump the next program + 10 bytes or so after that.  I was just wondering if there was a more elegant way to define the address of the end of a program?

Code: [Select]

the_end:

Frequently, executable memory is read-only. You may need to work around that. What's your OS?

Best,
Frank

homebrew OS like menuet or mikeos...it was late at nite and my brain was fried and it does seem like a stupid question after some sleep.  I don't know what I was looking for...anyway...thanks for no snarky comments...I'll sleep on any further questions before asking them.

No such thing as a stupid question. Although we did used to say, "ASCII foolish question, get a foolish ANSI."
