File No. S360-29 Form C28-6571-3 I , Systems Reference Library IBM System/3S0 Operating System PL/I Language Specifications This manual is a description of the full facilities of PL/I to be implemented under the System/360 Operating System. However. the reader should not assume that all facilities will be available at initial release. Manuals for speci- fic System/360 implementations will be released later. Another publication will be issued specifying a subset of the facilities of the language described in this manual. This subset is planned for implementation under the System/360 Disk and Operating System.
