Static file validation and tracing

HCL Link validates a static input file in a compiled map only once, when the map loads, and produces a trace file only if the static file fails validation.

HCL Link validates other map inputs each time the map runs, and logs them in the map trace file as specified by the map settings.

When you trace a static input file and the static file passes validation, the map trace file describes the static input as an existing work file. For example, you might trace two map inputs. Input 1 is not a static file and the input is invalid. Input 2 is a static file that passed validation during load. The trace file includes messages similar to the following:

   X'0002' (all_employees example).

   INPUT 1 exists, but its type is in error.
