[Computers say the darndest things]

     Does anyone out there know how CALL LINK is used in XBASIC?  The info I
got when I called TI appears useful, if somewhat cryptic.  According to them,
this is how it is done:

	 0.  CALL INIT

	 1.  Enter the program into the Low Expansion RAM with successive
	     CALL LOAD statements.  This example is to direct-load a program,
	     as opposed to using CALL LOAD with a file-name.

         2.  Enter the following:
	     CALL LOAD(-31878,0,"",8196,63,248,"",16376,80,76,79,84,32,32,39,20)

   In hex:   CALL LOAD(8314,0,"",2004,3F,F8,"",3FF8,50,4C,4F,54,20,20,27,14)

	 3.  In the program, this is accessed by CALL LINK("PLOT",96,I,S,C),
	     I,S,C are the parameters passed to the "PLOT" routine.

     The stuff entered into 3FF8-3FFF is the program name(in this case PLOT with
two trailing spaces to fill out the name), followed by the starting address of
the program[The 27,14 or h'2714(dec 9992)].

     Can anyone tell me what is in location h'8314?  My E/A manual just says
"system usage" or some such.
