Programming
languages
Let's assume that we
have studied the problem, designed a logical plan (our flowchart or
pseudocode), and are now ready to write the program
instructions. The process of writing program instructions is called coding. The
instructions will be written on a form called a coding form. The instructions
we write will be recorded in a machine-readable form using a keypunch,
key-to-tape, or key-to-disk, or entered directly into computer memory
through a terminal keyboard.
The computer cannot
understand instructions written in just any old way. The instructions must be
written according to a set of rules. These rules are the foundation of a
programming language. A programming language must convey the logical steps of
the program plan in such a way that the control unit of the CPU can interpret
and follow the instructions. Programming languages have improved throughout the
years, just as computer hardware has improved. They have progressed from
machine-oriented languages that use strings of binary Is and Os to
problem-oriented languages that use common mathematical and/or English terms.
There are over 200
problem-oriented languages. The most common of them are COBOL, FORTRAN, PL/I,
RPG, BASIC, PASCAL.
COBOL
COBOL was the most widely
used business-oriented programming language. Its name is an acronym for Common
Business-Oriented language. COBOL was designed to solve problems that are
oriented toward data handling and input-output operations. Of course, COBOL can
perform arithmetic operations as well, but its greatest flexibility is in data
handling. COBOL also was designed as a self-documenting language. Self-documenting
languages are those that do not require a great deal of explanation in order to
be understood by someone reading the program instructions. The self-documenting
aspect of COBOL is made possible by its sentence like structure and the very
generous maximum symbolic field-name length of 30 characters. With a field-name
length of up to 30 characters, the name can clearly identify the field and its
purpose.
FORTRAN IV
The FORTRAN IV language is
oriented toward solving problems of a mathematical nature. The name FORTRAN
comes from the combination of the words formulatranslation.
The version of FORTRAN IV has been designed as algebra-based programming
language. Any formula or those mathematical relationships that can be expressed
algebraically can easily be expressed as a FORTRAN instruction. FORTRAN is the
most commonly used language for scientific applications.
PL/I
PL/I stands for
Programming Language I. It was designed as a general-purpose language
incorporating features similar to COBOL for data handling instructions and
features similar to FORTRAN for mathematical instructions. PL/I is much more
than a combination of the good features of both COBOL and FORTRAN, as it has
many capabilities that are unique. Yet, although PL/I is one of the most
versatile and the most powerful of the programming languages, it is not the
most commonly used. COBOL and FORTRAN have been available for a longer period
of time than PL/I, and many more users work with those languages.
