Himem with prodos basic?

[j_2001_m@dejanews.com (Jm)]

I made an assembly language program that I need to interface with my
prodos basic program. The problem is what addresses should it go in?
Right now I'm loading it into the first hires graphics page. It seems
to work there but will prodos basic start scribbling all over it if I
make my program too long? I tried doing himem:(whatever hex 3500 is in
decimal) but then I got a "no buffers available" message when I tried
to load files. My apple 2c has 128K of RAM I think. Also, when I use &
to call the program, how would I type paramaters for it? Would it be
"& 3 2" or "&3,2,3" or what? And how does the program get them, are
they pushed onto the stack or something?
