How to Enter Startup Override Keywords

The operator's console prompts for and accepts returned override values.

To override a parameter, enter the appropriate override value in response to the following prompts issued at startup time:

ENTER SYSTEM VERSION—Allows the operator to override the DC/UCF version number. The version number is provided in one of the following ways:
- Supplied in the #DCPARM macro for the system
- Specified in startup JCL or commands for the system
ENTER PARAMETER OVERRIDES—Allows the operator to override system generation and #DCPARM parameters. In response to this prompt, the operator enters startup override keywords, as listed in Startup Override Keywords.
The system continues to issue the ENTER PARAMETER OVERRIDES prompt until the operator terminates the prompting sequence. To terminate the prompting sequence, enter a line with no data.
