Datasets

Datasets specified in steps that are executed on the host can reside either locally or on the host. By default, the RJSE facility automatically uploads or downloads datasets as necessary. However, if you want to override the default for one or more datasets, use the following JCL extensions:

```
%UPLOAD=[ YES | NO | AUTO ]
```
- YES Upload the dataset referenced by the DD
- NO Do not upload the dataset referenced by the DD
- AUTO Let RJSE determine whether or not to upload the dataset referenced by the DD (default)
```
%DOWNLOAD=[ YES | NO | AUTO ]
```
- YES Download the dataset referenced by the DD
- NO Do not download the dataset referenced by the DD
- AUTO Let RJSE determine whether or not to download the dataset referenced by the DD (default)
```
%PDSMEM=[ ALL | ONLY ]
```
Use this in conjunction with %UPLOAD or %DOWNLOAD. RJSE ignores this setting if the dataset is not a PDS.
- ALL Upload/Download the entire PDS of the dataset referenced by the DD
- ONLY Upload/Download only the specified member of the dataset referenced by the DD (default)

Note: RJSE issues messages indicating the actions it performed to create, upload, download, and delete datasets. Use these to fine tune your dataset specifications.
