   ZLT (Z-Ssytem Library Typer) will type crunched, squeezed, LZH-encoded,  or
normal text files or library members.  ZCPR3.0 or better is required.   ZLT is
not limited to typing one file at a time and may be instructed to display  all
files or library members  matching  an  ambiguous file  specification  ("?" or
"*").   ZLT recognizes Z-System named directories.   As installed,  files with
certain extensions (.COM, etc.) may not be displayed (see below).

   Original (12/15/87) by  Bruce Morgen which  was based on  LT29,  with  file
extraction and parsing code removed.  Original LT (10/2/84) by C. B. Falconer,
adapted from Steven R. Holtzclaw's "LUXTYP (06/10/83)".

  Syntax   ZLT [dir:]afn [. [/]options]
           ZLT [dir:]libname afn [[/]options]
           
 Options     0..9  <--  set intercharacter delay
             Q     <--  quiet operation
             P     <--  paging
  
   Optionally, quiet operation, intercharacter delay,  and/or  paging  control
can be specified as the  third  command  line  parameter,  with  or  without a
leading slash ("/") before the option.   While  a file is being displayed, the
user can strike a digit (0..9) to control the display speed,  or ^K, K, k, ^C,
C, or c to cancel the  display.   ^Z turns off page  pausing (use ^Z again  to 
turn it back on), and ^X causes ZLT to skip to the next file in the series, if
more than one file was matched, or abort if only one file was being displayed.
In addition, at each page pause,  the SPACE bar turns up one line instead of a
whole page (hit any other non-abort character to turn up the next page).

 ZLT Notes - 1/3 

   a. Vs 1.5 updates (9/12/91, Howard Goldstein):
      - Fixed option parser again. 
      - Removed code that ignored directory specs when Wheel byte off.  
      - Removed all conditional assembly.
      - Fixed built-in help message to  reflect default settings of  Q  and  P
        options.

   b. Vs 1.4 updates (9/6/91, Howard Goldstein):
      - Linked with new UNLZH module to support latest LZH compression.
      - Added CFG file name to configuration  block so  CFG  file can be found
        automatically even if program is renamed.
      - Fixed a minor bug in the command line option parser.
      - Replaced several JP's with JR's.
      - Now linking with ZSLIB which contains the old PARMLIB modules.
 ZLT Notes - 2/3 

   c. Vs 1.3 updates (11/1/89, Carson Wilson):
      -- adds LZH file support.
      -- adds "P" option to print without paging.
      -- Makes "P" and "Q" options installable defaults which are toggled at
         the command line.
      -- the default line limit for nonwheels is now 0 (no limit).  Use ZCNFG 
         to install a limit.

   d. Vs 1.2 updates (7/22/89, Carson Wilson):
      -- adds variable inter-character delay like PAGE.COM has.
      -- history is now in separate ZLTHIST.DOC file.
      -- translated to  Z80 opcodes  and  expanded  external  labels to full 7 
         characters for use with SLR tools.
      -- adds  "Q"  option which  suppresses all non-error  messages and extra
         LFs, sending to the screen the exact contents of a text file only.
      -- allows help only for  exactly  two "/"  characters, or no parameters.  
         Now possible to type files named "/" if needed.
      -- Changes a few exclude types.  Now excludes .NDR, .ENV, BIN, ZIP.
      -- adds patch points for Quiet and speed options.
      -- cleans up, shortens code with Z80 instructions; improves help screen.
 ZLT Notes - 3/3  

   e. Vs 1.1 updates (9/12/88, Bruce Morgen):
      -- fixes command name print routine to strip high bits.
      -- re-implements more frequent pause checking.   
      -- makes disabling of paging with ^Z a toggle.   
      -- disallows wildcards within LBRs for CP/M 3.x.
      -- truncates symbol names  to 6 chars to  allow  assembly with RMAC,  as 
         well as M80 and SLRMAC.

 Installation 

   No installation is required under ZCPR, however,  you may choose to further
customize your copy of ZLT by using ZCNFG on it.  To configure ZLT with ZCNFG,
place ZLT15.COM,  ZLT15.CFG,  and  ZCNFG.COM in  the  same  directory and type 
'ZCNFG ZLT15'.  ZCFNG will provide you with several installation menus.
