From Wikipedia, the free encyclopedia

COMTRAN (COMmercial TRANslator) is a programming language which served as the forerunner to the COBOL language. Developed by Bob Bemer, in 1957, the language featured the first programming language element known as the Picture Clause.

[edit] Picture Clause

The Picture Clause element defines the length of any given datum, much like a dictionary defines words. In particular the Picture Clause determines whether the datum contains letters and numbers, and other characteristics of the data, including format, size, and type.
