On IRIX systems, this routine is in lliibbffoorrttrraann..ssoo which is linked by
default when compiling programs with the MIPSpro 7 Fortran 90 compiler
or when compiling programs with the --ccrraayylliibbss option to the MIPSpro
7.2 F77 compiler.
The subroutine PPXXFFCCLLEEAARREENNVV 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 KKIINNDD==88 for integer, real, complex, and logical arguments; on
IRIX, the default kind is KKIINNDD==44.
The following argument is used with this subroutine:
_i_e_r_r_o_r An output integer variable that contains a status of zero if
all environment variables were cleared.

This example shows how to use the PPXXFFCCLLEEAARREENNVV 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
