SYSVAR - 2 - 1. INTRODUCTION *************** The memory region from & 7000 to & 7300 is reserved for so-called system-variables, that is, for variables that inform about the system activity and determine do some system activities. Variables are determined by location (hexadecimal-address) and a name, such as is used in MONITOR HANDLING MANUAL. Variables have their initialization values for individual languages BASIC (I, G, F possibly D) and system (S). BASIC language interpreters individually use this same area like MONITOR ROM. This area is linked to the area of system variables. <FF>
