*
* DESCRIPTION: This file describes function prototypes and data type
*              definitions used for Setjmp functions.
*
*              The <setjmp.h> header relates to the C phenomenon known as setjmp/longjmp.
*              It is used to escape out of the current situation into a previous one.
*              A typical example is in an editor, where hitting DEL breaks off the current
*              command and puts the editor back in the main loop, though care has to be
*              taken when the DEL occurs while executing a library function, since
*              some of them are not reentrant.
*
*

* SPECIAL CONSIDERATIONS:

*               __SetJmp_PC	rmb	2	; actual Long Jump "to" address in code (16 bit Address)
*               __SetJmp_SP	rmb	1	; Don't need to save the Status Reg, X 0r Acc?
*               __SetJmp_Y	rmb	1	;Y Reg

*               __SetJmp_PC	rmb	3	Program Counter, actual Long Jump "to" address in code (24 bit Address)
*               __SetJmp_SP	rmb	2	Stack Pointer   Don't need to save the Status Reg, X 0r Acc?
*               __SetJmp_Y	rmb	2	Y Reg
