ISPF PRIMARY OPTION MENU

View & Edit Entry Panel

BROWSE

Browse allows you to scroll up and down through your data or listings.

If the data is wider than the screen, you can scroll left and right.

To scroll, enter one of the four scroll commands (UP, DOWN, LEFT, or RIGHT).

To change the number of lines or columns being scrolled, change the scroll amount

field.

SEQUENCE NUMBERING:

The three commands that control whether NUMBER mode is on or off areNUMBER, RENUM, and UNNUM.

The AUTONUM command controls whether AUTONUM mode is on or off. If

AUTONUM mode is on, the data is automatically renumbered at save time, provided

NUMBER mode is also on.

EDIT DISPLAY MODES:

The following topics are presented in sequence, or may be selected by

number:

1 CAPS Mode - Controls whether data read from the display is to be treated as upper

case only, or as upper/lower case.

2 HEX Mode - Controls the screen display format to allow data to be displayed in

hexadecimal format.

3 NULLS Mode - Controls whether the fields on the screen will be written with

trailing blanks, or trailing nulls.

TABBING:

Edit supports three distinct types of tabbing:

- Software tabbing. After each interaction, edit positions the cursor to a new line or to

a new position in the current line within the current display window.

- Hardware tabbing. Edit will format the display so that the keyboard tab keys can be

used for entering/changing columns of data.


2/38


- Logical tabbing. A special tab character is defined which, when entered with input

data, causes the data to be shifted into specified columns.

RECOVERY:

If RECOVERY mode is on, edit keeps track of any changes that you make

while editing data.
