CBASIC (1981) 5 CPM

Digital Research CBASIC is a BASIC implementation that "compiles" basic code in to interpreted byte code that is run using a royalty-free runtime. BASIC source code is not needed to run a program. CBASIC was a popular programming language under CP/M. There were also versions for MS-DOS. MBASIC's rounding errors that were sometimes troublesome for accounting. machine code. Later versions also included support for GSX graphics extensions.

DRI Access Manager (1986) 1 DOS CPM

Access Manager is a database programming library sold by Digital Research. It supports key fields, b-tree indexes, record locking, and deleted records. It is designed for use with Digital Research language products including DR C, CBASIC, PL/I, and Pascal MT+, and may be used alongside the Display Manager programming libraries. There were versions for both CP/M and MS-DOS.

MP/M (1981) 4 CPM

Multi-Programming Monitor Control Program (MP/M) was a multi-user version of CP/M created in 1979. It could run on 8080 or Z80 based computers. Eventually it was ported to the 8086 and was named MP/M-86. It eventually assimilated technology from CP/M-86 and became Concurrent CP/M-86, later evolving into Concurrent DOS.
