3.4 Error messages
In practice, now and again errors occur when programming barcode activations,
particularly during testing of an application. Because the least defective barcodes
stand out without the appropriate reading device, error messages are an integrated
part of the barcode solution. These are printed out in place of the barcode symbol to
make the task of detecting errors easier for you.
The error messages are printed in plain text in a checked rectangle, e.g.:
, or
The following error messages exist:
Data too long
The length of the base data exceeds the defined maximum size for this barcode.
Data too short
The selected barcode requires a minimum number of characters, which has not been
reached in the base data.
Wrong char: xxx (where xxx = ASCII numeric value)
The selected barcode does not allow the specified ASCII character, which actually
occurred in the base data. Change the base data or use a different barcode, which
contains the character in its character set. If, for instance, the error message “Wrong
char: 121” occurs, then the letter “y” illegally appears in the base data, which is
intended for a numeric barcode (121 as the ASCII value for “y”).
Invalid param.
Values, which do not comply with the rules or are specified as being too high or too
low, are set for the parameters p, h, v, b or s in the call sequence.
Number not odd
The selected barcode requires an odd number of characters. The base data,
however, consisted of an even number of characters.
Number not even
The selected barcode requires an even number of characters. The base data,
however, consisted of an odd number of characters.
