CBASIC 1.x

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.

It featured 14-digit binary-coded decimal (BCD) math which eliminated MBASIC's rounding errors that were sometimes troublesome for accounting.

Later Compiler versions (CB80 and CB86) could compile to native machine code. Later versions also included support for GSX graphics extensions.
