One of the main features of Concord is the Control File.
The Control File is at the centre of the Concord system, and a lot of problems with data input, processing and producing reports may be the result of either incorrect control file set ups, or adjustments necessary to the Control File to enable the Concord user and or user groups to get the most from the Concord package.
NB: The assumption is that Users and/or User Groups have been set up correctly as per our chapter User Maintenance <UM>, prior to Control Files being set up.
