NullSubscripts

Allow null subscripts on global references.

Synopsis

[Miscellaneous]    NullSubscripts=n

n is either 1 (true) or 0 (false). The default value is 0.

Description

When NullSubscripts is enabled (n = 1), null subscripts are allowed on global references. When this parameter is not enabled, a null subscript causes a <SUBSCRIPT> error. InterSystems recommends leaving this setting disabled.

Instead of using the Management Portal, you can change NullSubscripts in the Config.MiscellanousOpens in a new tab class (as described in the class reference) or by editing the CPF with a text editor.
