Using a Perfect Format Field
Date, time and numeric masks have shortcut keys and auto-fill features:
When you enter a Perfect Format field you are in overtype mode. Pressing the [Insert] key toggles between insert and overtype mode. Insert mode is ignored in date and time masks. This is because, for example, allowing 09/22/2002 to become 01/92/2200 is forbidden.
When deleting or backspacing in a field using a date or time mask, the data to the right of the edit cursor is also deleted. This is because, for example, allowing 09/22/2002 to become 92/22/002_ is forbidden.
Data must match the mask of a field when pasting. If the data does not match a field’s mask the paste will be ignored.
To select an entire field, press the [F2] function key.
