Barcode BC 128 PLSQL code

Hi All,

We have written a custom PLSQL package to generate barcode strings for our XML/RDF/PDF reports.

It will generate a string as : Start Charater || Text || Check Digit || Stop Character.

We are facing issues in barcode scanning for few strings where check digit is coming as chr(32) or null.

Can someone provide us some referenece code for generating this barcode string for BC 128 fonts.

Regards

Sukhpreet

v_text_len                 NUMBER             := 0;

v_text_char        VARCHAR2(1);
