PROMPTING MESSAGES
A prompting message tells you that required information is missing or
that information you supplied was incorrectly specified.
A prompting
message asks you to supply or correct that information.
For example,
data-set-name is a required operand of the CALL command; if you enter
the
CALL
command without that operand the system will prompt you for the
data-set-name and your listing will look as follows:
READY
call
ENTER DATA SEn' NAME -
You should respond by entering the requested operand, in this case
the data set name, and by pressing the RETURN key to enter it.
For
example if the data set name is ALPHA. DATA you would complete the
prompting message as follows:
ENTER DATA SEn' NAME-
alpha. data
TO specify whether or not you want to receive prompting messages, use
the PROMPT or NOPROMPT operand of the PROFILE command.
This command is
described in the section, "Starting and Ending a Terminal Session".
sometimes you can request another message that explains the initial
message more fully.
If the second message is not enough, you can
request a further message to give you more detailed information.
To request an additional level of messaqe:
1.

your terminal session.

a response.
