/*	Long jumps are implemented as follows:  			    */
/*									    */
/*		1).	Routine "setjmp" is called to setup a special 	    */
/*			buffer for return.  The return address, stack 	    */
/*			pointer and frame pointer are saved.  This allows   */
/*			the calling program to do the proper number of 	    */
/*			"pops".		    				    */
/*									    */
/*		2).	At some later time, the procedure "longjmp" is	    */
/*			called.  The programmer sees a return from the	    */
/*			previous "setjmp" as the result.		    */

/*	a:								    */

/*		longjmp(env,val);					    */
/*									    */
/*	Setjmp returns a WORD of 0 on first call, and "val" on the 	    */
/*	subsequent "longjmp" call.  The longjmp call causes execution to    */
/*	resume at "a:" above.						    */
