Semi-Automatic Allocation of Data Storage for Pact I

摘要

The function of PACT is to compile a machine-language code from a given PACT pseudo-language code. In this sense PACT shortens the gap between the computational model and the final machine code by performing much of the intervening work. The paper is primarily concerned with the system which was designed to allocate machine storage locations for the operands which are involved in PACT pseudo-operations. The system was made to allocate storage locations automatically up to the total capacity of the high-speed memory and to allow the user some convenient means for constraining this allocation when necessary. No provision was made for automatic secondary storage allocation.
