In Figure 2-19, the is next to line 2 of the display. Line 2 shows the top item
in a scrollable list of sources. Note that a
has appeared on the right of the
bottom line. This indicates that the
button may now be used to scroll through
the list, and that the top item on the list is displayed. As soon as you press the
button, three things happen:
1. The list scrolls down one item (only line 2 scrolls)
2. A
appears on the right of line 1 of the display. This indicates that there is
one or more items above the item displayed on line 2.
3. The
at the left of line 2 disappears. This is because the * indicates the
current selection or the default selection, and you have scrolled the default
selection offscreen, and have not yet selected an item from the list.
NOTE
The contents of the lists on line 2 and line 4 will
vary as follows.
Initial Screen - ‘From’ Line
The list on line 2 in Figure 2-19 (the ‘From’ line) will include every drive and
every magazine slot that has a cartridge in it (you cannot get a cartridge from a
slot or drive that is empty).
Initial Screen - ‘To’ Line
The list on line 4 of Figure 2-19 (the ‘To’ line) will include all of the valid
destination choices, that is, drives and slots that are empty (you can’t put a
cartridge into a slot or drive which already has one in it.)
Scroll List - ‘To’ Line
There is another limitation on the ‘To’ list. If you have selected a drive on the
‘From’ screen, the ‘To’ list can include only slots. If you have selected a slot on
the ‘From’ screen, the ‘To’ list can contain only drives.
Let us assume that you want to load the cartridge that is in Slot 4 into any
available drive. Use the
button to scroll line two to Slot 4. The display
appears as shown in Figure 2-20.
