Redraw field If specified,the command reloads affected window fields with the new value of the data field,after it has performed the operation; note that this takes the 'All windows' option into account
All windows If specified,the command applies to all open window instances, rather than just the top open window instance


This command clears the data from the specified field or current selection. The data is lost and is not placed on the clipboard. If you do not specify a field, the current field’s data is cleared (assuming there is a selection).

In the case of a null selection when the cursor is merely flashing in a field and no characters are selected, Clear data will literally clear "nothing".

; checks if the value entered is over 5000. If it is, the value entered into the field
; is cleared and the cursor remains in the field.
