List Processing Functions

InstallShield 2016 » InstallScript Language Reference

Lists are used to store groups of related information. In InstallScript, there are two types of lists: string lists and number lists. Two sets of functions are provided to work with lists, one for each list type. List functions that end with "Item" operate with number lists. List functions that end with "String" operate with string lists. You cannot use number list functions on string lists and vice versa. Below are the functions to implement lists in a setup script.
