Operating the 5157 ACL Tape Drive   6-33
Initial Screen - ‘From’ Line 
The list on line 2 in Figure 6-26 (the ‘From’ line) will include the 
drive and every magazine slot that has a cartridge in it ( a cartridge 
cannot be selected from a slot or drive that is empty). 
Initial Screen - ‘To’ Line 
The list on line 4 of Figure 6-26 (the ‘To’ line) will include all of the 
valid destination choices, that is, all slots that are empty ( a 
cartridge cannot be placed into a slot or drive which already has one 
in it). If the drive is empty, it will appear on this list. 
Scroll List - ‘To’ Line 
There is another limitation on the ‘To’ list. If the drive has been 
selected on the ‘From’ screen, the ‘To’ list can include only slots. If 
a slot has been selected on the ‘From’ screen, the ‘To’ list can 
contain only the drive. 
Assume that the operator wants to unload the cartridge that is in 
DLT1 into any available slot. Use the ù button to scroll line two 
back up to DLT1. The display appears as shown in Figure 6-27.
