+/- Scroll the File Display Window up or down

+ | - Scroll the window by one screen forwards or backwards.

An empty command field (transmitted with DUE1) can be used to page forward, as well as "+".

++ | -- Position the window at the beginning or end of the file.

Data security: Entering ++ when displaying PAM files will position the window only at the last writable data block. Under TSOS, the window can be positioned at the PAM page on the other side of the Last Page Pointer.

Notes:

When Positioning to the end of a very large SAM file, long wait times can result, since the file has to be read completely by CFS. This process can be interrupted by pressing the K2 key (branch to BS2000 command mode), and then entering /INTR R. The window will be positioned at the place last read.

Positioning to the end of a very large, blocked (with STD,1) SAM file can be accelerated by using the command PBnnnn/#Bnnnn (see below for description). nnnn is the number of the last data block to have been written (LASTP entry). The record numbering in this case will be lost.

+n | -n Scroll the window n records forwards or backwards.
