ED, the CP/M Line Editor,ped initially for minicomputers in the 1960s, in particular to the DEC series of machines and the Data General Nova and Eclipse line. Anyone using a microcomputer with CP/M will immediately feel at home with ED if he has had some experience at operating system level on a minicomputer.

Using MBASIC,rsion used under CP/M-86 is known as BASIC-86, which is identical with MBASIC. It is an interactive programming language developed initially for teaching the principles of programming back in the late 1960s. Since then it has undergone many variations as each computer manufacturer has produced his o

CP/M Plus (CP/M Version 3.1),lled increases by a factor of two. At present 64K of RAM is the norm for the 8-bit micro and the step up to 128K has produced a problem. An 8-bit processor cannot address, directly at least, more than 64K. This is because the largest integer that can be stored in a Z80 processor address register of

CP/M-86,. CP/M-86 is a version of CP/M 2.2 and contains all the standard CP/M commands. Because of the greater addressing capabilities of the new 16-bit processors application programs written with CP/M-86 in mind can address up to a megabyte (1 048 576 bytes) of RAM. All files written by CP/M-86 are compat

Concurrent CP/M,micro, are protracted by the slowness of the data input and output. The input device is usually the keyboard, and even the speediest of typists cannot supply data at anything like the speed that it can be processed. Similarly, the speed of printers is far slower than the speed that the computer can
