|System Options under z/OS|
|Valid in:||configuration file, SAS invocation, OPTIONS statement, SAS System Options window|
|Category:||Files: External Files|
|PROC OPTIONS GROUP=||EXTFILES|
|z/OS specifics:||The LRECL= system option applies only to UFS files. It does not apply to native files.|
|See:||LRECL= System Option in SAS Language Reference: Dictionary|
|LRECL=n | nK | nM | nG | nT | hexX | MIN | MAX|
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 32,768 bytes, which exceeds the allowed maximum value.
|Range:||1 - 32,767|
specifies the logical record length as a hexadecimal number followed by an X. The first hexadecimal character must be in the range 0-9. For example, the value 0A0X sets the logical record length to 160.
specifies a logical record length of 1.
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 on 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 methods, SAS uses the value specified by the LRECL= system option.
Use a value for the LRECL= system option that is not an arbitrarily large value. Large values for this option can result in excessive use of memory, which can degrade performance.
