   EXFIND is a Z-System utility for RAS operators.  Used in conjunction with a
ZCPR alias script,  EXFIND searches an offline archive catalog and reports the
existance, or non-existance of requested files via the ZCPR registers.   Thus,
used as an extention to ZMD, existing files are not accepted as uploads.

   EXFIND's  sole  output is  through  the  ZCPR  registers,  where it reports 
success, or failure of the search; or optionally the number of hits.

    Syntax   EXFIND  [DIR:][FILENAME.EXT][=mask][/o]

   ...where "mask" is the filename or word to search for.   A single  optional 
parameter, "c",  causes EXFIND to  report the number of matches in registers 0 
and 1, the least significant  count in register 0 and the  most significant in 
register 1.  By default, EXFIND returns either 0 for no match or 1 for a match
in register 0.   In this case, the search is terminated on the first match (It
is assumed that the file has been sorted alphanumericly).   Lines with leading 
spaces or tabs are ignored, allowing for the file being commented.

 Patching 

   Two patch areas exist near the beginning of the program.  These are clearly
labelled:


 SIZREC>   which is set to 12 characters.   This determines the maximum number
of characters to compare.  Thus the catalog can contain, as in my case,  a key
a key which determines the application of the file, and a one line description
of the file.

 FILE>  which is the default  file to search.   The default file  may be over-
ridden from the command line.   Currently the default is  OFFLINE.DIR.  Change 
these to suit your application.

 The Alias Script 


ZMD	IF $1=R;ECHO P%>LEASE WAIT... ;EXFIND A0: =$2;IF 0 0;
	ZMD150 $*;ELSE;type a0:m ex;FI;ELSE;ZMD150 $* ;ZIF

   ZMD.COM has  been renamed  to ZMD150.COM  and  made  "system" so  as not to
appear in the normal directory display.   The file  "ex" contained in M.LBR is 
typed on the console  when  a  match is  found to explain to the user that the 
file  he is  attempting to upload  already exists and that  he should possibly 
select another file.
