L/P Dos is another attempt at making DOS CommandLiners feel more comfortable in the Windows 3.0 enviroment. This version is a Beta release of a future ShareWare product, it is free for distribution so long as all the files in the archive are kept intact and not modified in any way, shape or form. I am releasing this version for the sole purpose of testing, so please give it all you've got and try your best to crash it. (I may regret that statement!) My address is listed at the bottom of this introduction and I will gladly welcome all reports on L/P Dos, I want to make this something everyone NEEDS, not just puts on their system as another pretty. In return for helping me with L/P Dos I will register those people who contact me with reports of bugs or suggestions that will better the program, for absolutely nothing. Also, if someone wants to volunteer to help me out with the documentation, I will make it worth the effort.
To give you some background about L/P Dos... L/P Dos was developed using Microsoft's Visual Basic. For the most part all the standard DOS commands are supported and work the way they do from the command line except as noted below. Batch files are supported and must be named with an ".LPB" extension. Some examples are included in the Archive. The Batch file LPBATCH.LPB, contains working examples of a good many of the commands, try running it for a good demo. To stop any command that has scrolling output press the ESC key. You can start L/P Dos with a Batch file name on the command line and L/P Dos will run the Batch file before returning control to you. As an alternative, if there is a Batch file named LPDOS.LPB in the startup directory L/P Dos will immediately run the file upon startup. Some other points of interest are; Don't name a Batch file with the same name as a command, wierd things will happen (I'm still working on that one...) The command syntax is pretty unforgiving, but for the most part the interpreter in L/P Dos will catch a lot of the syntactical errors. For some reason with Visual Basic I can't always detect keyboard input from certain applications to reset the Saver so it won't activate if you're typing at the keyboard (Windows Write is a good example, I'm pretty sure it has to do with not using the Caret correctly, any suggestions are welcome.), so if the saver starts up when you are not expecting it set the saver delay time to a longer period of time. Mouse input always resets the Saver time. Make sure the .DLL files contained in the archive are in a directory in your DOS search Path, don't use L/P Dos to copy them there. (I tried on a friends machine...Windows wigs out big-time.. Although it is interesting to see a system error dialog scroll.. :D )
Don't know what else to tell you, more can be learned from playing with it than reading about it, so enjoy!
