CONTEXT function

The CONTEXT function lets you obtain information about object values that are saved in a context. You must first create the context with the CONTEXT command.

Return Value

The data type of the return value of the CONTEXT function depends on the arguments you provide. When you use the CONTEXT function without supplying any arguments, it returns a multiline text value that contains the names of all the contexts in the current session.

Syntax

CONTEXT ([context-name [UPDATE|name]])

Arguments

context-name: A text expression that contains the name of the context. Using the CONTEXT function with only the context-name returns a multiline text value that contains the names of all the objects saved in that context.
UPDATE: When you specify UPDATE with the CONTEXT function, the return value is the number of times values have been saved or dropped from the context.
name: The name of an object whose value is saved in the context. When you specify name with the CONTEXT function, the return value is the saved status or value of that object.
