Data File Organization and Addressing E-13
Monitoring Indexed Addresses
The offset address value is not displayed when you monitor an indexed
address. For example, the value at N7:2 appears when you monitor indexed
address #N7:2.
Example
If your application requires you to monitor indexed data, we recommend that
you use a MOV instruction to store the value.
File Instructions
The # symbol is also required for addresses in file instructions. The indexed
addresses used in these file instructions also make use of word S:24 to store an
offset value upon file instruction completion. Refer to the next page for a list
of file instructions that use the # symbol for addressing.
ATTENTION
File instructions manipulate the offset value stored in
word S:24. Make sure that you load the correct offset
value in S:24 prior to using an indexed address that
follows a file instruction. Otherwise, unpredictable
operation could occur, resulting in possible personal
injury and/or damage to equipment.
N10:2 will contain the data value that was added to T4:0.ACC.
