If TECO finds the logical name TEC$INIT, its equivalence string is
  assumed to be either a TECO macro or, if the string starts with a
  dollar sign ($), the rest of the string is assumed to be a file-spec
  containing a TECO macro to be executed every start up.  To disable
  the lookup of TEC$INIT, the qualifier /NOCOMMAND can be used.  To
  explicitly specify a start up TECO macro file, the qualifier
  /COMMAND=file-spec can be used.
