1 CALL_COMIS
  Syntax:   CALL_COMIS filename[(arg)] Y|N
  where:    filename  is the name of the file with the COMIS subroutine
            arg       is the (optional) argument with which the subroutine
                      will be called
            Y|N       decides if the file will be edited before compilation
  Defaults: arg = 0.0

  Calls a  COMIS subroutine  with argument  `arg'. You can  use this to do
  anything you want. However it is  probably most useful to do things with
  histograms you have read in with Mn_Fit and cannot do easily directly in
  Mn_Fit.  You will  be asked  whether you  want to  edit the  file or not
  before compiling it.
