In the ISPF mainframe environment, scrolling options are used to navigate through data displayed on the screen, such as datasets, member lists, or outputs. Scrolling allows users to view content that is not visible on the current screen by moving up, down, left, or right. ISPF provides both line commands and primary commands for scrolling, making navigation efficient and flexible for users handling large datasets or outputs.
Different Scrolling Options Available in ISPF -
Vertical Scrolling -
Vertical scrolling moves the content up or down by a specific number of lines or pages.
Horizontal Scrolling -
Horizontal scrolling shifts the content left or right, useful for datasets with wide records that exceed the screen width.
