NBASIC is a BASIC interpreter designed to mimic the operation of 8/16bit microcomputers of the early 1980’s like the Tandy Color Computer®, Apple ][e®, Commodore 64®, Texas Instruments TI-99/4A®, and others. The operating system that also included the BASIC interpreter was usually stored in ROM and started immediately upon boot up.

NBASIC works much the same way and is essentially a small operating system that handles memory management, input/output, file management, and command processing. The interface to the operating system is through the BASIC interpreter. To control NBASIC you enter commands in the form of BASIC statements. NBASIC interprets the command and performs the requested operation.

NBASIC is available in two versions, shareware and standard. The shareware version is free and does not include some of the features found in the standard version such as graphics, advanced editing, debugging, and configuration options.

All programs written with the shareware version of NBASIC will run on the standard version. Programs written with the standard version of NBASIC will run on the shareware version if statements and functions found only in the standard version are not used.
