Intermec Fingerprint v7.61 – Programmer’s Reference Manual Ed. 7 35

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:"

RUN

yields for example:

Files on lock:

SYS1 11

238 bytes free 11 bytes used

1 2 ... 32 33 34 35 36 37 38 39 40 41 42 ... 331 332
