Catalogs are implemented as ASCII files with the file type <TT>.cat</TT>. A MIDAS catalog has entries either for images or tables or fit files currently existing in MID_WORK and is then referred to as an Image, Table or FitFile catalog, accordingly. If a catalog is enabled (via <TT>SET/ICAT, SET/TCAT, SET/FCAT</TT>), new entries are added automatically whenever new frames are created, otherwise entries in a catalog have to be explicitly created via <TT>ADD/ICAT</TT>, <TT>ADD/TCAT</TT>, etc. <BR> Frames that are listed in a catalog may then be referenced by their name, as well as <BR> via <TT>#n</TT>, if <TT>n</TT> is the entry_no. of the frame in the currently enabled catalog, or <TT>#n,cat_name</TT> if the entry is in catalog <TT>cat_name.cat</TT> (only one catalog of each type can be enabled at any one time). <BR> <BR> The following commands are related to the use of catalogs: <BR> <BR> <TT>CREATE/xCAT</TT> <I>cat_name dir_specs</I> <TT>x = I, T, F</TT> for images, tables, fit files <BR> create catalog <I>cat_name</I> for images/tables/fit files, using <I>dir_specs</I>, <BR> which are the options of the host commands <TT>DIRECTORY</TT> (VMS) or <TT>ls</TT> (Unix). <BR> <BR> <TT>SET/xCAT</TT> <I>cat_name</I>; <TT>CLEAR/xCAT</TT> <BR> enable/disable automatic addition of entries for images/ tables/fit files in MID_WORK <BR> to catalog <I>cat_name</I> <BR> <BR> <TT>READ/xCAT</TT> <I>cat_name low,hi</I> <BR> display all entries of image/table/fit file catalog <I>cat_name</I> within given range <I>[low,hi]</I> <BR> <BR> <TT>ADD/xCAT</TT> <I>cat_name frame_list</I> <BR> add image/table/fit file entry(ies) specified in <I>frame_list</I> to catalog <I>cat_name</I> <BR> <BR> <TT>SUBTRACT/xCAT</TT> <I>cat_name frame_list</I> <BR> remove entry(ies) from image/table/fit file catalog <I>cat_name</I> <BR> <BR> <TT>EXECUTE/CATALOG</TT> <I>proc P1 P2 ...
