Added to Version 5.0.

answer = IsMember(string set_name, string row_handle)

Argument	Contents
set_name	The selection set to test
row_handle	The record handle of the record to test

A string, "True" if row_handle is a member of the selection set, otherwise "False".

//Open BDOCUMENTS\CALIPER\\< product name>\TUTORIAL\NElayers.wrkz

tutorial_folder = RunMacro("G30 Tutorial Folder")

wrkz = OpenWorkspace(tutorial_folder + "NElayers.wrkz")set_name = "Selection"

row_handle = "4465"

answer = IsMember(set_name, row_handle)

ShowMessage("It is " + answer + " that the record with the handle " + row_handle +

" is in the " + set_name + " set")

// Create a formula field that indicates which records are in set Selection

If IsMember("Selection", GetRecord() ) then "Selection" else ""

IsMember() returns "False" if row_handle does not exist.
IsMember() can be used in formulas, to do different things for different selection sets.
