Rational Developer for System z
Enterprise PL/I for z/OS, Version 3.8, Language Reference Manual

SYSPRINT and SYSIN

Two files are provided that can be used by any PL/I program. One is the input file SYSIN, and the other is the output file SYSPRINT. These files need not be declared or opened explicitly. For SYSIN, the default attributes are STREAM INPUT, and for SYSPRINT they are STREAM OUTPUT PRINT. Both file names, SYSIN and SYSPRINT, have the default attribute EXTERNAL, even though SYSPRINT contains more than 7 characters.

The compiler does not reserve the names SYSIN and SYSPRINT for the specific purposes described above. They can be used for other purposes besides identifying SYSIN and SYSPRINT files. Other attributes can be applied to them, but the PRINT attribute is applied by default to SYSPRINT when it is declared or opened as a STREAM OUTPUT file unless the INTERNAL attribute is declared for it.
