ZOOM
In CHAR, LHEX, HEX, or TABL display formats, if you want to display all data in a particular record without having to scroll left or right, you can “zoom in” by moving the cursor to the record, then pressing the Zoom function key (F2). To zoom out, press the Zoom function key (F2) again.
You can only use ZOOM with Tape Browse (option 4.1) and Tape Update (option 4.3).
For further details, see Zooming in to see all of a record.
