The LoadProfiles(filename) command loads the profiling data stored in filename for all the procedures in the file.

The LoadProfiles(filename, proc1, proc2, ...) command loads the profiling data stored in filename for the specified procedures, proc1, proc2.

By default the profile data is merged into each procedure's profile table. In this case LoadProfiles does not return anything.  However, you can specify the output = table option which instructs the LoadProfiles function to return a table of the profiling data, similar to the one returned by Build.

LoadProfiles performs two checks while loading profile data from file. If one of these checks fail, the profiling data for that procedure is not loaded and a warning is printed. The first check determines if the name associated with the data being loaded is the name of a procedure.  The second check verifies that the number of rows of data in the file matches the number of statements in the procedure definition.

If a procedure appears more than once in the file (as might happen if SaveProfiles is called with 'append'), then the multiple rtables of profiling data are merged.
