Controlling printed line length

You can limit the length of the printed line produced by a PRINT file by either:

RECSIZE must include the extra byte for the print control character; it must be 1 byte larger than the length of the printed line. LINESIZE refers to the number of characters in the printed line; PL/I adds the print control character.

Do not vary the line size for a file during execution by closing the file and opening it again with a new line size.

Since PRINT files have a default line size of 120 characters, you need not give any record length information for them.
