[Transcription of page 1, owing to extremely faded original. This Summary doesn't appear in the published text] Programme Organisation and Initial Orders for the EDSAC by D.J. Wheeler University Mathematical Laboratory, Cambridge SUMMARY This paper gives the methods by which programmes are designed on the EDSAC which is a typical automatic calculating machine Orders for the machine are represented outside the machine in a form different to the binary form used to represent them inside the machine and the necessary translation is done during the input of orders. This system allows the use of a more flexible system of representing orders than the binary form used inside. This system also enables sub-routines to be adjusted by means of parameters and enables a library of sub-routines to be made which eases the construction of long programmes. A complete simple example is worked out in detail to illustrate the principles involved.
