Manager.sys can use the "Interex program Alfred" but operator.sys can not. I get errors like this - does anyone know what I should change? Gathering Log File Information ... UNABLE TO OPEN FILE LOG0500.PUB.SYS **** PROGRAM ERROR #19 :PROGRAM QUIT .PARAM = 1111 ABORT: ALFRED2.PROG.CSLXL NM SYS a.00a23314 dbg_abort_trace+$24 CM SYS % 226.404 SWITCH'TO'NM'+%4 SUSER1 CM PROG % 0.453 LOG'QUERY+%335 SEG' Program terminated in an error state. (CIERR 976) thanks ...
