Display, Ver.1.0
as of
October 30, 1980
DISPLAY.COM allows displaying an ASCII file on a 24 line
terminal, with commands similar to Digital Research's ED.COM
(but without any of the editing facilities).
Using DISPLAY.COM
For example: DISPLAY FILENAME.TXT<cr> ,will envoke the
display program and load the entire secondary entry
(FILENAME.TXT) into memory, for subsequent display of the first
23 lines of that file. Various commands can then be issued from
the terminal keyboard which will manipulate the display of the
file.
The commands shown below with a preceding "n" indicates that
an optional unsigned integer value can be specified to envoke
"n" iterations of the command. When a command is preceded by a
"-" sign, the command will cause display of the file in a
direction towards the start of the file. Unsigned integer
values are assumed to be positive values (i.e., "+") and
therefore "+" need not be specified. Also, the buffer pointer
will stop display at the top or bottom of the file if too large
a value of "n" is specified.
Command: Operation performed:
======= ===================
B Move pointer to beginning of file and display page.
-nP Move pointer minus n pages and display page.
nP Move pointer plus n pages and display page.
0P Move pointer to beginning of buffer and display page.
-nL Move pointer minus n lines and display page.
nL Move pointer plus n lines and display page.
nD Discard n pages, refill buffer and display the
current page.
0D Discard all data up to the current pointer, refill
buffer and display the first page.
E Exit DISPLAY and return to CP/M.
^C Control-C, exit DISPLAY and return to CP/M.
<cr> Carriage return, move pointer to next page and
