- n
-
specifies the logical record length in multiples of 1 (bytes);
1,024 (kilobytes); 1,048,576 (megabytes); 1,073,741,824 (gigabytes); or 1,099,511,627,776
(terabytes). For example, a value of 32 specifies
32 bytes, and a value of 32k specifies 32,767
bytes.
Default: |
256 |
Range: |
1-32767 |
- hexX
-
specifies the logical record length as a hexadecimal value.
You must specify the value beginning with a number (0-9), followed by
an X. For example, the value 2dx sets the logical
record length to 45 characters.
- MIN
-
specifies a logical record length of 1.
- MAX
-
specifies a logical record length of 32,767.
The logical record length for reading or writing external
files is first determined by the LRECL= option in the access method statement,
function, or command that is used to read or write an individual file, or
the DDName value in the z/OS operating environment. If the logical record
length is not specified by any of these means, SAS uses the value that is
specified by the LRECL= system option.
Use a value for the LRECL= system option that is not an arbitrary large
value. Large values for this option can result in excessive use of memory,
which can degrade performance.
Operating Environment Information for z/OS Users: Under z/OS, the LRECL= system option is recognized
only for reading and writing HFS files. ![[cautionend]](../../../../common/63294/HTML/default/images/cautend.gif)
