Specifying word The word number is specified directly to
addresses specify the 16-bit word.
@@@@
Specifying offsets for bit In brackets, specify the number of bits
addresses to offset the specified starting bit
address.

A symbol can also be specified for the
starting bit address. Only Holding,
Work, DM, and EM Area addresses can
be used regardless of whether a physi-

address is specified, the contents of the
word is used directly as the offset.
