This chapter describes the use of collection and list objects defined within the Multiframe Automation Interface. List objects are an import class of object as they provide a means of rapidly accessing and modifying data for a large group of objects with only a small number of subroutine calls between Multiframe and the host application used to automate Multiframe. A good understanding of the behaviour and use of list objects will ensure that your scripts execute rapidly. The first two sections of this chapter describe the properties and methods of collection and list objects. The final section of this manual describes the Find method which is common to both list and collection objects.
