Summary

Eight copies of a programming manual for the CSIRAC computer, written by GW Hill, CSIRO Division of Mathematical Statistics for the Computation Laboratory University of Melbourne.

The manual is a user friendly' programming manual for the Automatic Electronic Computer, CSIRAC. It is described, on the front cover, as a "manual in English language for automatic programming."

The Introduction to the manual explains:
"The time required to learn to prepare a calculation for execution by the electronic computer, CSIRAC, is greatly reduced by the INTERPROGRAM system. The user writes steps of the calculation as commands in English language, using any convenient names for values arising in the calculation. The flexible INTERPROGRAM vocabulary can be used with little training and understood with even less. The computer translates INTERPROGRAM language into its own language and executes the required calculation. Use of the computer to construct its own program of operations is known as 'automatic programming'. . . . The system can be extended by increasing the vocabulary or by replacing the arithmetic system by one providing greater precision . . ."

The manual provides a detailed description of how to program CSIRAC. The Introduction includes some explanation of what is meant by programming:
"To 'programme the calculation' means to draw up a list of commands, each of which calls on an operation that the machine can perform and which together will do what is required. For this purpose the programmer will need to know which commands the machine can perform and how to organize these operations into a complete programme. It is sometime helpful, but not necessary, to understand the physical details of machine organisation ...
In many programmes, most of the commands are copied from previously tested programmes, which have been organized into a 'library' of routines."
