VARDIR parameter    ==  VARDIR=dirPath
                    --  default: VARDIR='${DGROOT?&:/var/spool/delegate}'

This parameter seems be obsolete after DGROOT has become standard in DeleGate/6.0. It specifies the default base of sub directories like DGROOT except for ACTDIR and TMPDIR. The default value of VARDIR is the value of DGROOT.
