5.65 SCLPROOT (SCLP base directory)

5.65.1 Function

The SCLPROOT system parameter sets the SCLP base directory. If a directory is given then SCLP disk
I/O for the specified directory path is enabled. NONE disables SCLP disk I/O.

A subsequent list-directed IPL resets the path to the location of the .ins file, and a subsequent CCW-type
IPL disables SCLP disk I/O.
