NAME
     PXFCLEARENV - Clears all environment variables

SYNOPSIS
     SUBROUTINE PXFCLEARENV (ierror)
     INTEGER ierror

IMPLEMENTATION
     UNICOS, UNICOS/mk, and IRIX systems

STANDARDS
     IEEE standard interface for FORTRAN 77

DESCRIPTION
     On IRIX systems, this routine is in libfortran.so which is linked by
     default when compiling programs with the MIPSpro 7 Fortran 90 compiler
     or when compiling programs with the -craylibs option to the MIPSpro
     F77 compiler.

     The subroutine PXFCLEARENV removes all environment variables for the
     current process.

     When using the CF90 compiler or MIPSpro 7 Fortran 90 compiler on
     UNICOS, UNICOS/mk, or IRIX systems, all arguments must be of default
     kind unless documented otherwise.  On UNICOS and UNICOS/mk, default
     kind is KIND=8 for integer, real, complex, and logical arguments; on
     IRIX, the default kind is KIND=4.

     The following argument is used with this subroutine:

     ierror  An output integer variable that contains a status of zero if
             all environment variables were cleared.

EXAMPLES
     This example shows how to use the PXFCLEARENV routine to clear the
     environment variable for the current process.

                program pxftest
                integer ierror
                CALL PXFCLEARENV(ierror)
                if (ierror .eq. 0) then
                   print *,'PASSED: pxfclearenv test'
                else
                   print *,'FAILED: pxfclearenv test'
                endif
                end

     This example may display:

          PASSED: pxfclearenv test
