Addressing Words
To address a group of consecutive words in memory, use one of the
following formats:
Format: Example:
wordaddr,size $N0:47,20
filesym:offset,size @FILE_A:15,25
wordsym,size @WORD_1,20
You can only address a group of words as the source field in an assignment
command. The destination must be a file that is as large as, or larger than,
the source range.

Example for Addressing Consecutive PLCĆ3 Words
$ N 15 : 0, 20
11236
Delimiter
Address of first word
to be transferred. Number of words to
be transferred.
Addressing a single word is similar only without specifying a size.
Format: Example:
wordaddr $N0:47
filesym:offset @FILE_A:15
wordsym @WORD_1
The scanner interprets wordaddr as an octal value if the addressed word is
in an input or output file. Otherwise, it interprets wordaddr as a
decimal value.
You cannot use the pointer data table specifier in an assignment command.
To access words in the pointer section of the PLC-3 data table, you must
use the PLC-3 extended addressing format. For example:
$E3.1.12.0.5.0 (1st word of pointer 5)
$E3.1.12.0.5.1 (2nd word of pointer 5)
