╘HE DEFAULT MEMORY LOCATION (BYTE) THAT STARTS ┬┴╙╔├ PROGRAMS IS 2049, BUT THIS CAN BE CHANGED BY CHANGING THE POINTER 43/44 CONTENT. ╙IMILARLY THE POINTER 55/56 CONTAINS THE HIGHEST LOCATION A ┬┴╙╔├ PROGRAM IS PERMITTED TO USE, AND IT OFTEN IS CHANGED BY THE USER TO PROTECT A PROGRAM AND/OR DATA THAT ARE LOCATED AT HIGHER LOCATIONS.

╔F THESE POINTERS ARE TO BE CHANGED THEN IT MUST BE DONE BEFORE ENTERING THE PROGRAM. ╒NLESS YOU HAVE DONE SO ALREADY AFTER PROGRAM 1 (ABOVE) WAS LOADED, USE PROGRAM 101 TO SEE, AND WRITE DOWN, THE CONTENTS OF BYTES 43 TO 56.
╞OR EXAMPLE, IF NOT ALREADY DONE SO, TYPE IN PROGRAM 1 (SEE ABOVE) NORMALLY, WITH DEFAULT POINTERS. ╘HEN CHANGE THE BYTE 44 TO WHEREVER YOU WANT PROGRAM 2 TO START, AND ADD NEW FOR ┬┴╙╔├ TO CHANGE POINTERS. ╞OR THIS EXAMPLE:
