Indicates if a piece of text (or a text list) is contained within another text list. The function is case-sensitive.

Syntax

@IsMember( textValue ; textListValue )
@IsMember( textListValue1 ; textListValue2 )

Parameters

textValue

Text.

Text list.

Text list.

Text list.

flag

Boolean
• Returns 1 (True) if the textValue is contained in textListValue
• Returns 0 (False) if not
• If both parameters are lists, returns 1 if all elements of textListValue1 are contained in textListValue2

In processing lists, @IsMember differs from a simple = test. An = returns True if the pair-wise comparison of two entities has even one member; that is, it is not empty.

For further details on pair-wise operators, see the topic Operations on lists.

@IsMember returns True only if the first parameter is an exact match, or a subset of the second parameter which is a list.
