Pg. of GC20-1819-2 Rev March 30, 1979 by Supp. SD23-9024-1 for 5748-XX8 When you want to execute a ICP function with a PP key, or you want a PF key to execute a series of commands, you must use the logical escape symbol (") when you enter the SET command. Par example:
cp set pf5 immed edit test file"tbo"tinput line"'file sets the PP5 key as:
EDIT TEST PILEIBOIINPUT LINEIFILE You cannot set lowercase characters in a PF key.
The above examples use the IMMED operand of the SET command, which
specifies that the function is performed as soon as you press the PF key. You can also set a key so that it is delayed; that is, the command
or data line is placed in the user input area. Then, you must press the
Enter key to execute the command. You may modify the line before you
enter it. This is the default setting (DELAY) for program function keys.
For example, you might set a key as: QUERY DISK X(I} When you press this PP key, the command line is placed in the user input
area, with the cursor positioned following the "(I)" logical character
delete symbol; you can enter the mode letter of the disk you are
querying before you press the Enter key to execute the command. If you
enter 'A', the resulting command as seen by CMS is 'QUERY DISK A'. You can set all of your program function keys in your PROFILE EXEC, so they are set each time you load CMS. You can change a PP key setting
any time during a terminal session, according to your needs. If, for
example, you discover that you are repeating several procedures a number of times, and the procedure does not lend itself to being written into
an EXEC, you could use your program function keys.
All the lines in an EXEC procedure are scanned, and
strings are truncated to eight characters, so if you

For more details on setting PP keys, see the Controlling the Display Screen During a CP or CMS session (other than an EDIT session) messages and
warnings from the system operator or other users are highlighted. This
distinguishes these messages from other output and lessens the
possibility of important messages being lost or ignored.
A major feature of a 3270 display screen is the screen status area,
which indicates, at all times that you are on, the current
operating condition your virtual machine is 1n. Understanding the
status conditions can help you use CMS on a 3270 more effectively. The
screen status area indicates one of six conditions: 340 IBM VM/370 CMS User's Guide

indicates that the ter.inal is waiting for a line to be read by the
control program. You can enter only CP commands when the screen status
area indicates a CP READ.
