Problems of PL/I for system programming
Martin E. Hopkins · 1971
A group within the Computer Science Department of the IBM T. J. Watson Research Center is now engaged in the design and development of System/A, an experimental operating system to support a variety of user activities with multiprocessing hardware. PL/I has been chosen as the system implementation language. Work with the language has shown that it is very good for system programming. However, there are problems. A number of minor annoyances can be circumvented rather easily but there are a few more basic problems which often stem from the fundamental concepts of PL/I.
