COMAL was actually created as a mixture of the prevalent educational programming languages of the time, BASIC and Pascal, and was meant to introduce structured programming elements in an environment where BASIC would normally be used.
In the early 1980s, Apple Computer won a contract to supply Apple II computers running CP/M and COMAL to Irish secondary schools.
In 1990 Thomas Lundy and Rory O'Sullivan produced the definitive text on COMAL Programming. They matched and compared COMAL with BBC Structured Basic.
COMAL is available for:

IF condition THEN instructions ENDIF
Loops:
FOR number:= 1 TO 1000 DO PRINT number ENDFOR
Print statements with variables:
