SYSTEM_DEFAULTS - Establishing Default Parameters

All of the constraints can be assigned a default value. The default value is the value that is used for any constraints that are not specified on a matching level selector. These default values are assigned in the SYSTEM_DEFAULTS section of the GVBDBFON SYSIN file. The SYSTEM_DEFAULTS section begins with the SYSTEM_DEFAULTS command. This command can be abbreviated as SYSTEM.

All of the constraints (except for the above noted restrictions) can be specified in the SYSTEM_DEFAULTS section. Any constraint values assigned in this section will become the default values for those constraints. Any constraints that you do not assign a default value will have a value assigned to them by the OPEN intercept routine. The OPEN assigned values are discussed under each of the constraint topics earlier in this manual.
