I have a simple request for anyone who is has a real DEC VT100 or compatible terminal (VT100, VT220, VT320, VT420, VT510) and especially VT100 software emulations, either as standalone software or as part of a PDP-11 emulator such as Ersatz-11. In respect of the latter, I have been using the Ersatz-11 PDP-11 emulator to support VT100 emulation with more than 24 lines for a few years. In particular, as part of the implementation, when the Range Escape Sequence is used to begin the Scrolling Region at a line less than 24 for the TOP and a line at the bottom of the screen for the BOTTOM, I use: <ESC>[16;255r to scroll between line 16 and the bottom of the screen. For real DEC VT100 terminals with the AVO option, there is ONLY one size for the number of lines, namely 24 lines. Since I can't ATTACH files to be sent to classiccmp, below are two files which can be used to erase the screen, set the scrolling region to line 16 at the top and line 99 or line 255, respectively, at the bottom of the screen. If the any VT100 (compatible) terminal or emulated VT100 terminal set for 24 lines is able to handle setting the scrolling region in this manner, each file with FIFTY lines should begin starting to display "Line 1 of File" of the file on line 12 of the "terminal" and "Line 2 of File" on line 16 of the "terminal" the and end up showing approximately six lines of the file at the bottom of the screen as the previous lines of the file scroll off the TOP of the scrolling region (at line 16 of the terminal) with just "Line 1 of File" remaining on line 12 of the "terminal". I would very much appreciate learning the results of sending both files to a DEC (or emulated) VT100 terminal. If they act the same was as Ersatz-11, the results will be identical with using 24 in place of 99 or 255. Jerome Fine P.S. When the file is transferred to the system, replace <ESC> with octal 33!!!!!!!!!!!!!!!!!!!! KED can be used under RT-11. The user eliminates each <ESC> and enters TWO <ESC> characters instead. Alternatively, if you can remember the first line correctly, you can enter the complete file in about 2 minutes by duplicating (cut and paste) the other 49 lines. ----------------------------------------------------------------------------------- <ESC>2JESC>[12;1HLine 1 of File<ESC>[0;99r<ESC>[16;1H Line 2 of File Line 3 of File Line 4 of File Line 5 of File Line 6 of File Line 7 of File Line 8 of File Line 9 of File Line 10 of File Line 11 of File Line 12 of File Line 13 of File Line 14 of File Line 15 of File Line 16 of File Line 17 of File Line 18 of File Line 19 of File Line 20 of File Line 21 of File Line 22 of File Line 13 of File Line 14 of File Line 15 of File Line 16 of File Line 17 of File Line 18 of File Line 19 of File Line 20 of File Line 21 of File Line 22 of File Line 23 of File Line 24 of File Line 25 of File Line 26 of File Line 27 of File Line 28 of File Line 29 of File Line 30 of File Line 31 of File Line 32 of File Line 33 of File Line 34 of File Line 35 of File Line 36 of File Line 37 of File Line 38 of File Line 39 of File Line 40 of File Line 41 of File Line 42 of File Line 43 of File Line 44 of File Line 45 of File Line 46 of File Line 47 of File Line 48 of File Line 49 of File Line 50 of File ----------------------------------------------------------------------------------- <ESC>2JESC>[12;1HLine 1 of File<ESC>[0;255r<ESC>[16;1H Line 2 of File Line 3 of File Line 4 of File Line 5 of File Line 6 of File Line 7 of File Line 8 of File Line 9 of File Line 10 of File Line 11 of File Line 12 of File Line 13 of File Line 14 of File Line 15 of File Line 16 of File Line 17 of File Line 18 of File Line 19 of File Line 20 of File Line 21 of File Line 22 of File Line 13 of File Line 14 of File Line 15 of File Line 16 of File Line 17 of File Line 18 of File Line 19 of File Line 20 of File Line 21 of File Line 22 of File Line 23 of File Line 24 of File Line 25 of File Line 26 of File Line 27 of File Line 28 of File Line 29 of File Line 30 of File Line 31 of File Line 32 of File Line 33 of File Line 34 of File Line 35 of File Line 36 of File Line 37 of File Line 38 of File Line 39 of File Line 40 of File Line 41 of File Line 42 of File Line 43 of File Line 44 of File Line 45 of File Line 46 of File Line 47 of File Line 48 of File Line 49 of File Line 50 of File -----------------------------------------------------------------------------------
