CBASIC (1981) 5 DOS

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.
