...TC-shell¹

ORAC-DR requires tcsh for full functionality from the system setup. If tcsh is not available the startup scripts (oracdr_ufti etc) will not set the specified UT date (the argument is ignored). In this case the ORAC_DATA_IN and ORAC_DATA_OUT environment variables must be set up explicitly. Additionally, the oracdr command must include the `-ut' option as specified in the oracdr documentation.
