See STATIC.TXT for information about how to use the files. To compile the programs, use the commands: tpc /b windinst tpc /b windtest The .TPU and .EXE files were compiled with Turbo Pascal 5.5. If you are using an earlier compiler version, you MUST recompile the units. Execute windtest to run the test program. Press any key to quit. Next, run the test installation program windinst. Change various window colors and the title string. Then, run windtest again to see the effects of your changes. Because I wrote these examples for publication in a magazine, they are rather terse--for example, you have to enter colors by number. But, they demonstrate all you need to know to write your own installers with TCUNIT. I'd appreciate your comments. Tom Swan Compuserve ID: 73627,3241
