or a cartridge location. If the cursor appears over the entire value, it is a multiple-
choice value.
3.3.4.1
Editing Multiple-Choice Values
If the item contains a multiple-choice value, the entire value will be overlaid with
flashing block cursors. Use the (UP) key to select the next value and the
(DOWN) key to select the previous value, then press EXIT when done. The list of
choices wraps around, so the operator can see all the choices by using just the (UP)
or (DOWN) key.
3.3.4.2
Editing non-Multiple-Choice Values
If only the first character of the value is highlighted with a flashing block cursor after
pressing the ENTER key, the value is either numeric, alphanumeric, or a cartridge lo-
cation. These values may be edited one character at a time, using the ENTER key to
select the character to be edited, and then using the (UP) or (DOWN) key to
change the character's value.
NOTE
The cursor wraps around from the last to the first character. Also, the ENTER, (UP) or
(DOWN) keys automatically repeat when held down.
3.3.4.3
Editing Numeric Values
Numeric values may be edited one digit at a time, or the entire value may be changed,
by simply incrementing or decrementing the least significant digit (or any intermedi-
ate digit). When incrementing the digit 9, it goes to 0 and a carry is added to the more
significant digits. The opposite effect is true for decrementing. This process will auto-
matically stop at the upper and lower limits of the valid range for each item. Remem-
ber to take advantage of the automatic key repeat feature by holding down either the
(UP) or the (DOWN) key.
The system will never allow making any value invalid. The choice for each digit is lim-
ited to valid values. For example, valid values for SCSI ID’s range from 00 to 15. The
range of some valid values may change with a system's particular configuration. In
this example, if the X1 digit was selected, then the value can be incremented all the
way from 00 to 15 and rolling over to 00 again by simply holding down the (UP)
key. Holding the (DOWN) key will decrement the value to 00 and stop there.
3.3.4.4
Editing Alphanumeric Values
Either the (UP) or the (DOWN) keys can be used to edit alphanumeric characters
one at a time. There are no carries or borrows to other characters. The choice for each
particular character will be limited to valid characters, which vary with the item and
the character’s position within it.
The following table shows the available alphanumeric characters (A/N) and their
hexadecimal (hex) equivalents. The characters occur in the order shown in the table,
starting with the “space” character, followed by the “A” character and ending with the
