CBASIC
This programming language may be used to instruct a computer to perform a task.

Listed below are all of the tasks on Rosetta Code which have been solved using CBASIC.

CBASIC was the commercial outgrowth of the BASIC-E compiler written by Gordon Eubanks as his Master's thesis while a student at the Naval Postgraduate School. CBASIC -- which was marketed for both 8 and 16 bit CP/M systems -- differed from many of the BASIC dialects of the day in two major respects: (1) line numbers were not required unless the statement was the target of a GOTO or GOSUB statement (and were in any event treated simply as labels) and (2) real (floating point) variables were implemented as 14-digit binary coded decimal (BCD), which, particularly in business and accounting applications, avoided round-off errors which purely binary floating point computations were prone to. Integer and string variables (which required % and $ suffixes, respectively) were also provided, as well as multi-dimensional arrays. Identifiers could be of any length, although only the first 31 characters were significant. CBASIC supported multiline user-defined functions with parameters passed by value but did not support recursion. CBASIC was implemented as a compiler-interpreter: the source code was compiled into an intermediate form, which could then be executed by invoking a run-time interpreter. A companion compiler, CB80, was offered that compiled to machine code.
