obsolete: Just use Set_attribute DF_FILE_STATUS inactivates a record by putting 0 in the buffer
                     // Inactivate Df_File {KEEP}
                     // if {KEEP} then we put the original rec back in buffer
   #IF !0>1
     #CHECK !2 "KEEP"
     Send Inactivate to DESKTOP !1.File_Number 1
   #ELSE
     Send Inactivate to DESKTOP !1.File_Number 0
   #ENDIF
