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 ,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. Carriage return, move pointer to next page and display -------------------------------------------------------------- Best regards, Kelly Smith, MP/M-Net (tm) Sysop 805-527-9321 (Modem, 300 Baud)
