   These exit macro values work with either exit() or return from main(),
   and avoid unnecessary warnings from the DCL command intrepretor.  They
   don't match VAX C's <stdlib.h>, which has 0 and 2 respectively.  Using 0
   for success works with VAXCRTL's exit() but requires additional compiler
   support in main() (which VAX C neglects to provide).  2 always provokes
   "%NONAME-E-NOMSG, Message number 00000002"; similarly for unfixed 0.
