| Data Set Options under z/OS |
Summary of SAS Data Set Options in the z/OS Environment
The following table describes both the data set options specific to z/OS and the portable data set options.
The See column tells you where to look for more detailed information about an option, based on the following legend:
| COMP | |
| LR | |
| NLS |
SAS National Language Support (NLS): Reference Guide |
The Engines column lists the engines with which the option is valid, based on the following legend:
Note: For the purposes of the following table, V7, V8, and V9 are the
same engine, and V7TAPE, V8TAPE, and V9TAPE are the same engine. ![[cautionend]](../../../../common/63294/HTML/default/images/cautend.gif)
