sdatabar - Convert an SDATA file into HP41 barcode
sdatabar [-e] < input_file > barcode_file
sdatabar is a program that reads an SDATA file from standard
input and writes the corresponding HP41 barcode file to
standard output. Records in the SDATA file containing
numeric data are turned into type 6 barcode rows, while
those containing alpha data are turned into type 7 rows.
Other SDATA records cannot be represented by HP41 barcode,
and are skipped, giving a suitable error message.
The output of sdatabar can be piped to a suitable barcode
printing program such as barps
-e HP82153 barcode wands with the version 1E ROM have a
bug which means they cannot read numeric data barcode
rows containing 10 or more data bytes. Unfortunately,
some HP41 real numbers require 10 bytes to represent
them in barcode format. If the -e option is given to
sdatabar, the program attempts to reduce the length of
the barcode by omitting the decimal point and adjusting
the exponent to compensate. This is not always
possible, in which case, a suitable message is written
to standard error, and the last mantissa digit is
omitted from the barcode.

The format of HP41 barcode is given in the book Creating
your own HP41 Barcode (Hewlett-Packard)
The format of the barcode file written by sdatabar is given
If data1 is an sdata file, and postscript is a postscript
sdatabar < data1 | barps 'Data
will print that file on the postscript printer.
The HP82153 wand can't accept data other than standard
numeric or alpha data, so some sdata files cannot be
translated correctly. Version 1E wands cannot read some
numeric data barcode, as described above.
