Abstract
In a large computer it is often desirable and convenient for an ordinary program to be able to establish for itself a logical connection to a peripheral device. This ability is normally provided through a routine within the operating system which may be called by any user program at any time. OS/360 lacks such a routine. For the batch job, peripheral connections can only be made through the job control language and this cannot be done dynamically at run-time. In the restricted context of TSO (IBM’s terminal system) a routine for establishing peripheral connections does exist, but it is extremely inefficient and difficult to use.
This paper describes how a suitable routine was written and grafted into the operating system of the Cambridge 370/165.
