Exbasic Level II
Exbasic Level II is a BASIC language extension for Commodore computers. It was developed between 1981 and 1983 and originally distributed commercially as a cartrige by Interface Age. Initially, it was available for Commodore PET computers of the CBM2000/3000/4000/8000 series, later for the VIC-20 and the C-64. A free version for the Commodore 64 was published in the 64'er magazine in the issue 04/1988 as the Listing of the month. The accompanying diskette contains both a program (V64.3) and a module version (V64.1). The description in this article refers to the 64'er version.
Loading and Starting[edit | edit source] For the cartridge version, switch off the computer, put the cartrige in the Expansion port and turn on the computer. In case of diskette or tape versions, the program must be loaded and started: LOAD "EXBASIC L II",8 RUN After this, 59 additional keywords are available, with DOS 5.1 support and function key mapping. Memory use[edit | edit source]The program uses 4 KBytes at $8000-$9FFF. Command addresses can be found starting at $9EA0, the keywords starting at $9EE8. Modified vectors[edit | edit source]
BASIC-Extension[edit | edit source]The focus of the Exbasic Level II extension is on convenient program development. The BASIC editor is supported by a number of commands and boasts a scrollable listing. The special features of the C64, however, are only partially supported. While there are a few commands for the sound, none for the high-resolution graphics. Keywords[edit | edit source]
