Data General Extended BASIC, also widely known as Nova Extended BASIC, was a BASIC programming language interpreter for the Data General Nova series minicomputers. It was based on the seminal Dartmouth BASIC, including the Fifth Edition's string variables and powerful MAT commands for matrix manipulation. In contrast to the compile-and-go Dartmouth BASIC, Extended BASIC was an interpreter.
To this, Extended BASIC added substring manipulation using array slicing, which was common on BASICs of the era, found on HP Time-Shared BASIC, Sinclair BASIC, Atari BASIC and others. This contrasts with the Microsoft BASIC style which uses string functions like LEFT$, and thus makes porting string code somewhat difficult.
Data General later purchased rights to a much-expanded BASIC which was released as Data General Business Basic. This added powerful database functionality and largely replaced Extended BASIC on DG platforms.
