Chapter 2 Program Instructions
CHDIR
Field of Application Statement specifying the current directory.
Syntax CHDIR<scon>
<scon> specifi es the current directory (see DEVICES)
Default: "c:"
Remarks
By default, the printer’s permanent memory ("c:" ) is the current directory,
which means the directory that is used if the Intermec Fingerprint instruction
does not contain any reference to a directory, for example FILES. This
implies that to access the temporary memory ("tmp:"), the storage part
of the RTC/Dallas key circuit ("storage:"), or an optional memory card
("rom:" or "card1:"), you must include such a reference in your instructions,
for example FILES "rom:".
The CHDIR statement allows you to appoint another directory than "c:"
as the current directory. Obviously, this implies that you must specify the
permanent memory ("c:") whenever you want to access it.
Example In this example, the current directory is changed to "lock:", all fi les
in "lock:" are listed, and fi nally the current directory is changed back
to "c:". (This example is only included to illustrate the principles of
changing the current directory. It is more effi cient to use FILES "lock:"
to read its contents.)
10 CHDIR"lock:"
20 FILES
30 CHDIR"c:"

yields for example:
Files on lock:
