Installing on a PC

Sd and Sdtty are two separate programs, that are both installed simultaneously. Whether you obtain them from the World Wide Web or by diskette, they are provided in the file `install.exe'. The two programs will share the same initialization file, and hence will use the same sessions, options, and accelerator keys.

(If you are running DOS, Windows 3.1, or NT 3.51, you can only use Sdtty, and you must obtain the file `install3.exe'.)

To install the programs, execute ("launch") the file `install.exe'. You can do this by double-clicking it in the Windows Explorer, by launching it during a Web download, or by starting the "Run" operation from the start menu and giving the location of the `install.exe' file. For example, you can install from a diskette by selecting "Run" and typing "A:install.exe".

If any pre-existing calling program files were in the `C:\Sd' folder, they will be saved in a folder with a name like `C:\Sd_pre3281' before the new version is installed. The installation will not damage or delete any sequence transcript files or initialization files.

If you have downloaded the documentation files in "bulk" form in self-extracting zipped archives, you can launch them also. The files are `textdoc.exe', `psdoc.exe', and `pdfdoc.exe'. Launch them in the same way as `install.exe'. They will unpack the appropriate text, Postscript, or PDF files into the directory.

When the installation is complete, the programs will be in the `Sd' subfolder of the `Programs' folder of the Start Menu. The installation procedure also leaves an Explorer open on the shortcut icons. There are several icons for starting Sd or Sdtty with various color schemes, for browsing the manual or release notes, and for editing the initialization file. You may copy any or all of these from the open Explorer to the Desktop and/or the Start Menu. To do this, perform a drag-and-drop operation, using the right mouse button. If the system asks, select "Copy Here". To place icons in on the Desktop, just perform a right-mouse drag-and-drop to any unused place on the Desktop. To place icons in the Start Menu, just drop them on the actual "Start" button in the lower left corner. When finished, close the Explorer by clicking the "X" in the upper-right corner.

(If you are running DOS, Windows 3.1, or NT 3.51, you must place the `install3.exe' in the folder in which you want Sdtty to operate (typically `C:\sd'), and launch it there. You can create a shortcut icon by copying the file `SDTTY.PIF' to the appropriate place. Use the PIF editor to modify it if necessary.)

You may delete the `install.exe' file at this point, along with any documentaion archives, perhaps saving copies on diskette.

You do not need to copy the shortcuts again when upgrading to a new version. Installing a new version requires only obtaining and launching `install.exe'.

You can, of course, copy the shortcuts anywhere, and edit them with the "Properties" operation of the Windows Explorer. Among the things you can do is put command-line arguments into them. For example, you can make another copy of the Sd icon on the Desktop (under a different name), and arrange for the program, when launched with that icon, to run in reverse video mode. Run the "Properties" operation on the copied icon, and change the `Target' specification on the `Shortcut' page from "C:\sd\sd.exe" to "C:\sd\sd.exe -reverse_video".
