CLEAR

Clears the screen. Any data typed on the screen but not saved on the CA VM:Director A‑disk is lost. The original screen is displayed again.

ENTER

Ends the PAINT command after saving the screen.

PF1

(HELP)

Displays a help screen that shows the functions performed by the twelve PF keys.

PF2

(ADD)

Adds a blank line to the screen below the cursor position. All subsequent lines are shifted down one line and the bottom line is lost. All field names below the inserted line are cleared and must be redefined.

PF3

(QUIT)

Ends the PAINT command without saving the screen.

PF4

(PROTECT)

Toggles the protection attribute associated with the current field. Protected fields cannot have data entered in them by terminal operators and are skipped over when the forward or backward tab key is pressed. However, if you assign a name to a protected field, a macro can move data to it by means of the SCREEN FIELD function.

Fields are initially unprotected (an operator can add data to it).

PF5

(DELETE)

Deletes the line on which the cursor is positioned. All subsequent lines are shifted up one line and a new blank line is inserted as the bottom line. All field definitions following the deleted line are cleared and must be redefined.

PF6

(HIGHLIGHT)

Toggles the highlight attribute associated with the field on which the cursor is positioned.

Fields are initially at normal intensity.

PF7

(MODIFY)

Toggles the Modified Data Tag (MDT) attribute associated with the current field. This tag causes the system to read data from the field even if the terminal operator does not enter anything in it, and is normally used for default parameters in unprotected fields.

Fields are initially unmodified.

PF8

(SCALE)

Displays or hides a horizontal scale on the line at which the cursor is positioned. When the scale is removed, the line’s previous contents are restored.

PF9

(NUMERIC)

If the terminal has the numeric lock feature, toggles the numeric attribute associated with the current field. Numeric locks restrict a terminal operator to enter only numeric digits 0 through 9, the period, minus sign, and dup key in numeric fields.

Fields are initially alphanumeric (an operator can enter any character in a field).

PF10

(FORMAT)

Toggles the format mode of the entire screen. In format mode, fields are delimited by the invisible start‑field character, and any attributes that have been assigned are in effect. In unformatted mode, all start‑field characters appear as visible field‑mark characters except the last character of the last line (this character remains a start‑field character to prevent the entire screen from being cleared if you press ERASE EOF); attributes are not in effect, and field definitions can be altered.

Screens are initially displayed in unformatted mode, where control characters are displayed and field definitions can be altered.

PF11

(DISPLAY)

Toggles the display attribute associated with the current field. This attribute determines whether data in the field is visible on the screen; it is generally used to hide passwords.

Fields are initially displayable.

PF12

(FIELD)

Displays the field identification menu. This menu shows the name of the current field, its length, line number and column position of the start field character, and the settings of the various attributes. You can set or change the name or any attributes of the current field when this menu is displayed.
