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
