There is every application you could think of for CP/M 2.2, Assemblers, compilers, spreadsheets, editors, and so on. Myself I like programming in forth, so the next few screen shots are of a FORTH CP/M 2.2 package running Pro-DOS.

Got my Pro-Dos Booted up, put the disk with forth on it in drive A. listed the contents [DIR], the file I need to run is Z80FORTH

The CP/M forth language is ready for you [no file, means I did not load a FORTH source file when we loaded the FORTH program].

Just to prove it works, add 1 + 1, and print the answer in FORTH language.

Just to prove it works, lets list all the forth commands this forth package knows, using the forth word VLIST, and it starts to list the forth "words" it knows about.

and the "words" keep listing. The forth "word" in this package "BYE" just quits the program and returns you to Pro-DOS system.
