In block 18, the first two letters identify SHIPALT
(SA), ORDALT (OA), field change (FC), or any other
appropriate instruction. Electronic equipment is always
identified by serial number, and only one piece of
equipment may be reported under a given JCN. If
several pieces of the same type of equipment are altered
by field changes, there must be one document for each
piece of equipment. Example:
A ship has four C-13 Mod 1 catapults, and field change
17 is to be installed in all of them. Each catapult will be
changed, and the changes will be reported on separate
documents showing a specific JSN and equipment
serial number. This will enable the computers to
identify which items of equipment have been changed
and which have not. It also will be reflected on the
readouts returned to the ship as part of its material

In block 35, a space follows each word, and words
that cannot be completed on a line are continued on the
next line with no spaces or hyphens inserted. On
deferred actions, the XXX's used to separate the trouble
from the desired corrective action must not be
separated. If they cannot be fitted in on one line, extra
spaces will be left blank on that line and the XXX's will
be put in the first spaces of the next line.
