Function: Display ASCII file on console
Usage:    Like CP/M's resident TYPE command (only better)

Version 1.9 (11-14-85) - Kaypro only (KPLD19.COM)

     Version  1.9 has been speeded up by adjusting the method  of 
line  and  string searching,  and I/O  usage.  Otherwise,  it  is 
similar  to  version  1.5.  Also,  a peculiar problem  was  side-
stepped:  by  using character input functions (BDOS f.# 1 and  6) 
and  BDOS f.# 10,  the latter would produce  mysterious  (single) 
characters,  the  same as the last entered character through BDOS 
#1  or  6.  Function  10  was used with  the  L(ine)  and  F(ind) 
searches.  The  algorithm was simulated with BIOS calls  and  the 
"problem" disappeared.

Version 1.5 (10-18-85)

     This  program  makes  viewing  an ASCII file  a  simple  and 
flexible convenience.  Each line is numbered.  You can quickly go 
to the top of the text or the bottom, or you may jump directly to 
a  particular line.  String searches are also permitted.  It  has 
particular  value in reviewing a document created by WordStar  in 
that  several  of the common printing features  (underlining  and 
boldfacing)  are  displayed  on the screen rather than  just  the 
control codes for the particular feature.  This latest version is 
submitted in two forms and has the added feature of "search  next 
string": 

     1)  KPLD15  - is  designed  for the  Kaypro  2X,  4,  10  or 
equivalent. It has installed code for underlining, reverse video, 
half bright and blinking. 

     2) LD15 - is a somewhat more generic form in which codes for 
underlining,  reverse video and half bright are marked within the 
COM file.  The marker (see below) immediately precedes the  code. 
Though  configured for the Kaypro,  it should be easily adaptable 
to  any CP/M-80 computer.  If the Kaypro video features  are  not 
desired  or  cannot be run as is,  the locations of  the  various 
codes follow which can be used to change the code.  Six (6) bytes 
have  been allowed for each video function code,  with each  code 
sequence  ending  with  a  dollar sign ($).  Use  DDT  to  access 
LD15.COM:


     A>DDT LD15.COM (cr)

and  then the DDT 'D' command to display the COM file  code.  The 
DDT  'S'  command lets you substitute your own computer  code  if 
necessary.

Starting location     Function        ASCII code marker
      (Hex)
       181           clear screen        cls->
       3D2           half bright ON      hbon->
       3EF           half bright OFF     hboff->
       40B           underline ON        ulon->
       428           underline OFF       uloff->
       47E           cursor ON           curon->
       49C           cursor OFF          curoff->
       4B8           reverse vid. ON     rvon->
       4D5           reverse vid. OFF    rvoff->

Where  your computer will not do any of the above,  if  necessary 
you can place the '$' in the first position after each marker  in 
order to bypass that screen function.

Version 1.2

     This  Line Displayer (LD) was designed on and for the Kaypro 
2X,  or equivalent (ADM-3A). It's a simple ASCII text viewer that 
can  be  used  in place of CP/M's TYPE command  and  employs  the 
following features for added flexibility:

FEATURES:

     1) Viewing page by page - forward/backward
                               single step
     2) Jump to specified line
     3) (Unique) string search
     4) Shows WordStar's Underline & Boldface
     5) Jump to start (Top) or end (Bottom) of text

Input commands:
     Lnnnn       = Will go to line nnnn, (e.g., L231)
     -           = backup 1 page
     CR          = forward 1 page
space bar or .   = forward 1 line
     T           = top of text
     B           = bottom of text
     E           = erase screen and print next page
     Fstring     = Find string (e.g., FHello)
                   U/L case matters!
  control-L      = continue search for string            <-- NEW 
     Q           = quit and return to CP/M
     ?           = print this menu

Comment:
     Programs like this are common. However, I've noticed several 
that appear to have been written in a high level language and are 
rather  sizeable,  the  most recent to come to mind being  ZTYPE. 
Ergo,  here is a smaller one.  While not perfect, I hope you find 
it handy.  If anyone is interested in the latest source  code,  I 
can  be reached at the above number or through  DC-To-Light  RBBS 
(408) 262-5150.
