Built-in Constants

Many of the Built-in subprograms take numeric values as arguments. Often, constants have been defined for these numeric arguments. A constant is a named numeric value. When passing a constant to a Built-in do not enclose the constant value in quotation marks.

Constants can only appear on the right side of an operator in an expression.

In some cases, a Built-in can take a number of possible constants as arguments. Possible constants are listed in the descriptions for each parameter.

In the following example, BLOCK_SCOPE is a constant that can be supplied for the parameter constant VALIDATION_UNIT. Other constants listed in the description are FORM, RECORD, and ITEM.

SET_FORM_PROPERTY('my_form', VALIDATION_UNIT, BLOCK_SCOPE);
