	I'm trying to use some assembly language routines in my 
	Basic program.  I stick the code in an interger array and 
	I then get the starting address of the code:

	for j=0 to 100
	  REM read the code from data statements
	read code%(j)
	next j
	Mac&=VARPTR(code%(0))

	This gives me Guru's of either  bad addressing or illegal
	instruction when the routine is called.

	The problem seems to be that the address of the
	code%(0) keeps moving aroung.  It seems to move so
	much that I can get the address right before I call the
	routine and still jump to the wrong place when I call it:

	Mac&=VARPTR(code%(0)) 
	CALL Mac&

	The routine is good.  I check it with the Metascope Debugger.
	Also before I discovered the address was jumping around, I
	started using a routine that was nothing but a RTS.

	I don't want to use the Library routines via the .BMAP files
	(ala AllocMem). I would like the program to be just one file.

	Any ideas or hearsay or (hopefully) the straight dope would be greatly
	appreciated.
