'''Minimal BASIC''' is a very small subset of the [[BASIC]] language. It is specified in ECMA Standard 55, ANSI X3.60-1978 and others. It has a rigorous test suite (initially NBSIR 77-1420 from 1978) to ensure that vendors supplying computer systems to the US Federal government met compatibility guidelines. |

The language is very limited: |
|||
* line numbers are required |
|||
* no string manipulation commands |
|||
* all variables must be defined/modified using the LET keyword |
|||
* the only loop structure is FOR … TO … STEP …, with loop parameters fixed at entry |
|||
* all programs must end with an END statement. |
|||
Implementations: |
|||
* Microsoft BASIC 5.0 for 8080 (BASIC-80, MBASIC for CP/M - 1981) claims compliance in its manual. |
|||

Compare with [[Full BASIC]]. |
