Screen control
This section describes OMEGAMON AI for CICS screen control functions.
- Scrolling
- The default scrolling keys are PF7/PF19 and PF8/PF20 (on terminals
with 24 programmed function keys). They are set to /UP and /DOWN (alias
/U and /D), and scroll one physical screen at a time. You can change
the default scroll amount with the OPTN command.You can also scroll by using the /UP and /DOWN INFO-line commands. The /UP and /DOWN commands accept the following arguments:
- nnn
- Scrolls nnn lines (nnn can be any number from 1—999).
- PAGE
- Scrolls a physical screen at a time.
- MAX
- Scrolls up or down the number of LROWS defined for your terminal; the short form of MAX is M.
- CSR
- Scrolls according to the current location of your cursor. If your cursor is on the INFO-line, the scroll amount is one page.
As an alternative to /UP and /DOWN, you can use the INFO-line command /TOP to scroll to the top of the logical screen and /BOTTOM to scroll to the bottom of the logical screen.
You can also type any of the /UP and /DOWN arguments (such as nnn, MAX, or CSR) on the INFO-line before you press the PF key to change the scroll amount. If, for example, you type MAX on the INFO-line and then press PF20, OMEGAMON® scrolls the maximum number of lines.
- Clearing the screen
- If a menu, screen space, or any commands display on your screen,
and you want to clear the screen, use the clear screen immediate command.
The clear screen command consists of two periods followed by two blanks.
Enter
..bb
in the input area of any line below the INFO-line to clear the screen below it. - Deleting comment lines
- To insert blank lines into a screen, use the following immediate command:
The variable nn indicates the number of lines to insert. The default setting is 1. Note that the nn argument must begin in column 6. OMEGAMON AI for CICS inserts the new lines before the line where you type the insert command. Therefore, all other lines currently on the screen below the inserted line shift downward. When the command executes, the line you typed over with the insert command restores to its original data..I nn
To delete lines from a screen space, use the .D nn immediate command, which works the same way as .I nn. When you do not specify the nn variable, it defaults to 1 deletion line.
You can also delete a block of data from the physical screen. To do this, enter
.DD
on the first and last lines of the block. - Displaying continuation lines of command output
- If your screen is cluttered with lines of comment text, and you want to clear the comments but retain other command text, you can use the /DCL INFO-line command or the .DCL immediate command. The /DCL command clears all comment lines on the logical screen, while the .DCL immediate command clears all comment lines below its entry line.
- Inserting and deleting lines
- Some major commands select a series of items. Often, the display
output does not fit onto one line. When this is the case, the major
command displays only the first line of output, and a plus sign appears
at the right of the line to indicate that more data is available. If you want to see a count of the number of items that a major command will select, enter a pound sign (#) in column 1 before the command. The following example shows that there are 20 online disks for the DISK command to display:
#DISK 20
- Continuing major command output
- You can use a number of different continuation characters and
commands to control the output display. Use these steps to control
the output display:
- Enter a less-than sign (<) in column 1 in front of a major command to generate all the output at once when it executes.
- After you issue a major command for the first time, you can put a number in column 1 to specify how many lines of the display to skip.
- You can repeat a major command to display only the next line of output.
- Continuing major and minor command output
- When a major command lists a series of items that continues for
more than one line, any minor command you enter after the major command
applies only to the last line of output. Therefore, if you enter a
minor command after the third line of major command output, that minor
command only generates information about the third line of items listed
by the major. Normally, the major and minor commands must be repeated
once for each line of available output.
The .RC command is a shortcut to this process. The .RC command automatically repeats the major and the minor until all available lines of data are displayed. Enter the major command once, followed by the minor commands, and then the .RC command below the minor.
- Delaying automatic updating
- The delay and hold features temporarily defer updating when you
are in dedicated or VTAM® mode
with automatic updating in effect (see the .AUP command).
- Delay feature
- While OMEGAMON AI for CICS is
automatically updating, you can continue to enter commands. If OMEGAMON AI for CICS detects a cursor
movement since the last update, it defers processing to avoid executing half-entered input.
The words
I/O Delay
appear on the INFO-line, and the screen is not updated for the number of cycles specified with the IODELAY keyword of the .SET command. - Hold feature
- If your screen display contains data that you want to study for
longer than the normal automatic update interval, you can use the
hold feature to temporarily freeze the screen image. To do so, home
the cursor, then move it back one space to the blank space in column
1 of the INFO-line. The words
Hold Mode
appear on the INFO-line, and the information on the screen does not change until you move the cursor away from row 1, column 1.
