COMAL
Structured programming
language
COMAL (COMmon Algorithmic Language) is a
computer language that combines the ease of
BASIC with the structure of PASCAL. Because
COMAL is easy to learn and powerful to use, it is
an ideal first computer language.
The major drawback with teaching or
learning BASIC as a first language is the
lack of program structure. Long
programs can become difficult to read.
For this reason, COMAL was developed.
