- 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.
-
