Waiting Control functions
Waiting control functions block the execution of a script until a response is received from the Event Manager. The return value from the function only indicates whether an error occurred before the function call was issued, but not whether the message received contains an error. Errors are stored in a separate variable. This can be checked and handled in the Control system using the function getLastError().
Waiting control functions can be identified due to the Assignment to "waiting control function" or a "W" in the Availability section of the function documentation.
User Interface Manager (UIM) functions:
Following functions open e.g. dialog windows, user input panels or alerts that must be acknowledged and lead to a stop in the program flow. For this reason, the functions are in the waiting control function section.
