Timeout in hundredths of a second.

• The function has no effect if a negative value is used.
• If this parameter is set to 0, the function processes all the pending events and takes control immediately.

Regardless of the parameter value, the optional processes of controls are always run. Remark: This parameter can correspond to:

• an integer corresponding to the number of hundredths of a second,
• a Duration variable,
• the duration in a readable format (e.g., '1s' or '10cs').

Type of event that can be run during the wait:

waitMouseAndKeyboard	The windows and the controls can be redrawn. The timers can be run. The mouse actions (click on controls for example) or the keyboard events can be run. Remark: This constant is equivalent to Multitask used with a negative value.
waitNothing	No event can be run.
waitRedraw (by default)	The windows and the controls can be redrawn.
waitTimer	The windows and the controls can be redrawn. The timers can be run. Remark: This constant is equivalent to Multitask used with a positive value.
