If trying to enter +DEL to delete a block of rows in a SYSVIEW Cmd field with only 3 spaces for input, the command won't fit.
The FILL command can be used in SYSVIEW display fields that are too small for the needed command.
To delete a block of rows in a Cmd field that is only 3 spaces, you can use the following command:
FILL CMD DEL 1-##
(The 1-## represents 'startrow-endrow'. You could also use 1/##, which would be 'startrow/numrows')
