Use the Specify alternate input file extended option to
specify a SAS data set name and SAS file names to be used as
the input source to the reporting software.  When inquiries
require multiple input files, you must specify all indicated
CA MICS equivalent files. If you are specifying a previously
saved input observation file, some files may not be needed as
they are already included in the saved file.  In this case,
you must enter a nonexistent file name.

A common use for this extended option is in the iterative
processing of an analysis program.  In this scenario, an
initial execution of the analysis inquiry inputs and subsets
data from a CA MICS file (possibly an archive tape file when
only one SAS file is required by the analysis/report),
retaining the selected data through the Save selected input
observations extended option.  Subsequent analysis executions
use this Specify alternate input file extended option to
reprocess the saved data.  In this way, you can economically
reprocess input data against a variety of analysis parameters
without revisiting the original CA MICS files.
