Syntax:     
        TRIM/CCD [in_fram] [out_fram] [im_sec] [del_flg]
\ys\pa 
        in_fram =   input frame to be trimmed; default is the name stored in
                    the keyword CCD_IN.
\ap\pa
        out_frame = resulting output frame; no default.

        im_sec =    image section to be extracted. Default is the section
                    stored in the keyword IM_SEC. 
\ap\pa 
        del_flg =   delete flag. Default is `NO'.
\ap\no
Note: 
        The command will not try to trim the input frame if that has already 
        been done. The descriptor CCDSTAT in the output frame is updated to 
        indicate that the frame has been trimmed.
