Description:

This subroutine hides selected widgets. <beg_at_name> is required, the subroutine will cancel if it is not received.

<beg_at_name> is the name of the first WIDGET to be hidden (Required).

<end_at_name> is the name of the last WIDGET to be hidden (Optional). If not PASSed, it will default to <beg_at_name>.

<beg_at_name> and <end_at_name> will be used in BEG AT/END AT commands to read the --- WIDGET file and set the WIDGET INVIS flag on all the widgets within the range.

Note that this does not delete the underlying --- WIDGET record. You can unhide --- WIDGET records via .WIDGET SHOW BY NAME, and you can delete them completely via .WIDGET DEL BY NAME
