1. A system for merging manual parameters with predefined parameters in an Information Management System (IMS), the system comprising: an Information Management System (IMS); a Time Sharing Options (TSO) module; a Single Point of Control (SPOC) module for managing a plurality of IMSs; a parse module configured to receive a command string having multiple nested manual parameters and configured to identify manual parameters within the command string; a build module configured to generate a parameter tree having manual parameter nodes, each manual parameter node representing one manual parameter, the parameter tree further comprising predefined parameter nodes, each predefined parameter node representing one predefined parameter; a search module configured to compare manual parameter nodes to predefined parameter nodes to identify parameter nodes having a matching parameter context; and a command module configured to generate a command string comprising at least one manual parameter from a manual parameter node having a matching parameter context.
