Because CODE 11 $ requires a large amount of scratch space while it is executing (1400 bytes), there
might not be enough memory available to execute CODE 11 $.
,
• During the 2-1/2 minutes while CODE 11 $ is waiting for a label to be scanned, the keyboard is
disabled. Only the expiration of the time or the scanning of a label will stop the decoder-pressing
the
[ATTN]
key will not. If CODE 11 $ is executed with an HP-7 SC installed in your HP 82718A
rather than an HP-7SD, you will have to wait the 2-1/2 minutes for the decoder to halt, since the
HP-7SC has no wand connector and thus cannot scan labels. If you are waiting for CODE11$ to
halt while running a program, press the
[ATTN]
key, and the program will halt as soon as the
2-1/2 minutes have passed.

Scans a single Code 39 label. Returns the decoded label as a string of ASCII characters and issues a high
tone if the label decoded successfully. Returns a null string and issues a low tone if the label did not
decode successfully or if 2-1/2 minutes go by with no scanning.

has been specified, the decoder will calculate the check digit and compare it to the
check digit scanned as part of the label (usually the last character of the label). The label will not decode
successfully unless these two check digits match. If CD I G I T OFF has been specified, the check digit
will not be computed or compared with the check digit in the label.
The longest label that can be decoded is 42 characters long, including the check digit. Labels longer than
42 characters will not decode successfully.
