barprt - Display an HP41 barcode file (diagnostic)
barprt < barcode_file
barprt
is a filter which reads an HP41 barcode file from standard
input. For each logical record in the barcode file, the
following is printed to standard output :
The number of bytes in that row of barcode
The values of those bytes in hexadecimal
The values of those bytes in decimal
Standard output can, of course be redirected in the normal way if it is desired to pipe the output of barprt to another program or store it in a file.
barprt is intended as a diagnostic program for debugging barcode creation and printing programs. It can be used to ensure that the output of a barcode creation program is as expected. A barcode printing program can be tested by using it to print a barcode file and then comparing the output of barprt applied to that file with the result of using the HP41 command WNDSCN to read the corresponding row of printed barcode.
See barcode(5) for details of the barcode file format
If bar1 is an HP41 barcode file then the command
barprt < bar1
will display the contents of that file in human-readable form on the user’s terminal
