You can view custom-defined functions to determine whether a function has been registered successfully and whether it is registered locally or globally. Custom-defined functions are not displayed until they have been created and registered.
For example, use the following MaxL statement to view the custom-defined functions in the Sample application and any registered global functions:
display function Sample;
The display function statement lists global functions without an application name to indicate that they are global. If the application contains a function with the same name as a global function, only the local function is listed.
