+DESCRIPTION
+ISTABLE is a very simple task which determines whether a specified
+input file is an STSDAS table, an APPHOT/DAOPHOT text database file or 
+neither of the above. ISTABLE first tries to open the input file as an 
+STSDAS table. If successful ISTABLE returns "yes" in the
+variable \fItable\fR and "no" in \fItext\fR and \fIother\fR. Otherwise
+ISTABLE  tries to open the input file as an APPHOT/DAOPHOT text database
+file by checking for the "#K IRAF" keyword.
+If the check is positive ISTABLE return "yes" in
+the variable \fItext\fR and "no" in \fItable\fR and \fIother\fR. If the input
+file is neither an STSDAS table or an APPHOT/DAOPHOT text database
+ISTABLE returns "yes" in the variable \fIother\fR and "no" in \fItext\fR
+and \fItable\fR.
