How can I generate QR codes from COBOL?

QR codes can be generated as bitmap files using the ZXing (Zebra Crossing) barcode scanning library.
All the file types supported by the W$BITMAP routine can be used.

Here are the steps to compile and run the sample COBOL program (QRSAMPLE.cbl) which will generate a png file representing the QR code, show this png on video and allow you to print it.

• Download the latest jar of 'core' and 'javase' from https://repo1.maven.org/maven2/com/google/zxing/
  At the moment this article is written, the latest jars are core-3.4.1.jar and javase-3.4.1.jar
• Copy the two jars to the 'jars' directory of the isCOBOL SDK
• Copy QRSAMPLE.cbl to a directory, open the isCOBOL Shell and change to that directory
• Compile with the command:

iscc QRSAMPLE.cbl

• Run with the command:

  iscrun QRSAMPLE
