May 19, 2021 Roger Lacroix

Enhancement to Exporting MQ Objects into Individual Files

March 11, 2021 Roger Lacroix

Yesterday, I wrote a blog item regarding Exporting MQ Objects into Individual Files. I forgot that the dmpmqcfg program can output the MQ Object information as 1 line rather than spanning multiple lines.
