+Happy New Year 2018. One of my new years resolutions was to write cleaner code, and in the spirit of out with the old and in with the new… I already use the RPG COPYRIGHT statement and the CL COPYRIGHT STATEMENT to store the copyright message and (more importantly to me) the Version or Release number […]
