MVDefined

Sets MVBasic handling of undefined variables system-wide.

Synopsis

[Miscellaneous]    MVDefined=n

Description

This setting defines MVBasic behavior when it encounters a reference to an undefined variable.

  • When 1 (true), if an MVBasic routine references an undefined variable, the system substitutes an empty string for the variable without showing an error.

  • When 0 (false), if an MVBasic routine references an undefined variable, the system generates an error. The default is false.

Examples

MVDefined=1

Range of Values

0 or 1. The default is 0.

Management Portal

On the page System Administration > Configuration > Additional Settings > Compatibility, in the MVDefined row, select Edit and choose true (selected) or false (cleared).
