The system uses five special screen characters to indicate the
status of certain screen messages. These special characters appear
in position three, four, or five of the lines in the message area:
- A vertical line (|) in position three indicates that required
action has been taken for the message and the system has deleted the
message.
- A horizontal bar (-) in position three indicates that the message
is for information only and requires no action from you.
- An asterisk (*) in position four indicates that the message is
a system message that requires action from you.
- An at sign (@) in position four indicates that the message is
a problem program message that requires action from you.
- A plus sign (+) in position five indicates that the message is
a problem program message that requires no action from you.
