+       Improve the way we handle the various parsing "states".  Until now
+       we've hard-coded the state transitions in the command definition
+       file, but that's error-prone and, worse, it's redundant--we can
+       figure out what state we're in anyhow.  We can cleanly handle
+       INPUT PROGRAM and FILE TYPE with a nested command-processing loop.
+       
+       * procedure.c (case_source_is_complex): Removed.
+       (discard_variables) No need to set pgm_state anymore.
