C THIS FUNCTION IS DESIGNED FOR USE ON A VMS AND ON A UNIX
C SYSTEM. IF YOUR SYSTEM IS VMS, COMMENT OUT THE LINE
C " CALL GETENV(NAMEIN, NAMEOUT)", FURTHER ON IN THIS FUNCTION.
C IF YOUR SYSTEM IS UNIX, MAKE SURE THE LINE IS NOT
C COMMENTED OUT.
C ON A UNIX SYSTEM, GETENV WILL CONSULT THE ENVIRONMENT
C FOR THE CURRENT ALIAS OF THE CHARACTER STRING CONTAINED IN
C 'NAMEIN'. THE ALIAS, IF IT EXISTS, OR THE ORIGINAL NAME IN NAMEIN
C WILL BE RETURNED.
