SORT/FCAT [cat_name] 
	sort a fit file catalog
\us\pu

\up\sy
Syntax:
          SORT/FCAT [cat_name] 
\ys\pa

\\
              defaulted to the currently active Fit File Catalog

\as\no
Note:
          Sorting is done according to the contents of the IDENT field in the
          catalog (i.e. usually the same as descr. IDENT).
\\
          The sorted catalog is first stored in a temporary file midtemp.cat,
          then the input catalog is deleted and, finally, midtemp.cat is
          renamed back to the original cat_name.
\\
          Therefore the input catalog should not be opened at the same time by
          e.g. another MIDAS session.
