globalglobal variableList
The global keyword makes a variable and its contents available to any handler in HyperCard. Changing the value of a global variable in any handler changes its value everywhere. Note: You must use the global keyword in each handler to declare the global variables you want to use. Global variables are not saved between sessions of HyperCard. Global variables are also lost under System 6's single Finder when a user (or handler) suspends HyperCard by launching another application with the open command. Examplesglobal myVar global pages,sections,chapters
