DELETE/ICAT [catalog] [conf_flag] [range]
	delete image frames with entry in catalog
\us\pu
Purpose: 
           Delete image frames (on disk) with an entry in given catalog.
\up\sy
Syntax:  
           DELETE/ICAT [catalog] [conf_flag] [range]
\ys\pa
           catalog = name of catalog, defaulted to currently active image
               catalog (cf. SET/ICAT command)
\ap\pa
           conf_flag = CONF  or NOCONF for confirming the deletion of each
               file involved, defaulted to CONF
\ap\pa
           range = low,hi indicating the range of catalog entries in which
               you want to delete frames;
\\
               (a single number m will be interpreted as m,m)
\\
               defaulted to 1,999999
\ap\no
Note:
           Warning: This command does not delete the catalog file itself, 
           instead all the images related to this catalog (i.e. those images
           having an entry in the catalog)!!!
\\ 
           To delete just the catalog file use the relevant host command
           ($DELETE (VMS) or $rm (Unix)).
\\ 
           If you decide not to delete a frame (conf_flag = CONF), then the
           corresponding entry of that frame is not removed from the catalog.
\\
           For confirmation answer y (for yes) or anything (for no).
