The +4 is a machine which supports expanded basic (4.0) so anything written in C64 or C64C basic (2.0 if I remember correctly) will run on the +4 with an additional set of basic commands as well: examples: 64 +4 LOAD"$",8 DIRECTORY or F3 LOAD"name",8 DLOAD"name" or F2 name SCRATCH RENUMBER DELETE Also .... The +4 does not run 64 commercial software (games, utilities) because the memory registers are completely different. The +4 does not have sprite graphics,but in graphics mode string variables can be used to simulate sprite-like features. The +4 has 4 built in programs: word-processor data-base spread-sheet spread-sheet graphics these progs are of limited quality. There is also a built-in assembly language editor accessed by the command MONITOR. all in all, if you intend to write your own software, the +4 is economical (about $99 retail) and 4.0 makes basic programing and disk management a breeze. HOWEVER, if you want to play RAMBO or Q-BERT , avoid the +4 like the black plague! AS a +4 user with 7 years experience I will be happy to answer any other +4 questions directed to me.
