Photograph of a computer programming diagram entitled "JOVIAL DELIMITERS". Diagram lists delimiters used in the JOVIAL programming language. A delimiter is a punctuation character or group of characters that separates two names or two pieces of data, or marks the beginning or end of a programming construct.

JOVIAL was developed by Jules Schwartz in the United States in1959, to write software for the electronics of military aircraft. The name is an acronym for Jules Own Version of the International Algorithmic Language.

This is one of a set of photographs of computer structure diagrams and computer programmimg instructions, probably used in the 1970s as aids in teaching computing subjects. The diagrams and instructions relate to several early models and systems of stored program computers dating back as far as the 1950s and including the CSIR Mark 1 (later renamed CSIRAC), the Cirrus, the Atlas, the IBM System/360 , the CDC 6600 System, and the Illiac IV.
