Promotes the interchangeability of BASIC programs among a variety of data processing systems. It establishes the syntax, formats of data, semantic rules, procedures for the detection and handling of errors and defines the keywords BASE, DATA, DEF, DIM, END, FOR, GO, GOSUB, GOTO, IF, INPUT, LET, NEXT, ON, OPTION, PRINT, RANDOMIZE, READ, REM, RESTORE, RETURN, STEP, STOP, SUB, THEN and TO. Technically identical to ISO 6373.

This International Standard is designed to promote the interchangeability of BASIC programs among a variety of automatic data processing systems.This International Standard establishes:a) the syntax of a program written in Minimal BASIC;b) the formats of data and the precision and range of numeric representations which are acceptable as input to an automatic data processing system being controlled by a program written in Minimal BASIC;c) the formats of data and the precision and range of numeric representations which can be generated as output by an automatic data processing system being controlled by a program written in Minimal BASIC;d) the semantic rules for interpreting the meaning of a program written in Minimal BASIC;e) the errorsand exceptional circumstances which shall be detected and also the manner in which such errors and exceptional circumstances shall be handled.Subsequent International Standards for the same purpose will describe extensions and enhancements to this International Standard. Programs conforming to this International Standard, as opposed to extensions or enhancements of this International Standard, will be said to be written in Minimal BASIC.Although the BASIC language was originally designed primarily for interactive use, this International Standard describes a language that is not so restricted.The organization of the International Standard is outlined in annex A. The method of syntax specification used is explained in annex B.
