Essential information
When your application accesses an existing RECORD file, PL/I
must obtain a record length value for that file. The value can come
from one of the following sources:
- The RECSIZE option of the ENVIRONMENT attribute
- The RECSIZE option of the DD:ddname environment
variable
- The RECSIZE option of the TITLE option of the OPEN statement
- PL/I-supplied default value.
PL/I uses a default record length value for an INPUT file when:
- The file is SYSIN. In this case, the value used is 80.
- The file is associated with the terminal. In this case, the
value used is 120.
