Microsoft Basic 1.0
Appearance
BASIC 1.0 is the standard BASIC language for Thomson computers (MO5, TO7, etc.), which is the reference for the entire range[1]. This is an implementation of Microsoft BASIC.
BASIC 1.0 interpreter recognizes the usual commands such as FOR..NEXT, GOSUB..RETURN, IF..THEN..ELSE, and DATA / READ / RESTORE statements. Advanced instructions like ON..GOTO and ON..GOSUB were also possible.
It allowed to introduce children from France to programming in the 1980s, since three languages were mainly taught: LSE, BASIC and LOGO. The school textbooks that offered programs in BASIC proposed them in BASIC 1.0 for Thomson and sometimes in ExelBasic for the Exelvision EXL 100.
