Servet,

Just to clarify a few items. On Friday in an email to the HLUG, I said:

Note that the above steps do not perform a compilation. They merely
consist of editing files.

Really, I need to add a few steps:
First, you should really completely read the Hydrolight 4.2 Technical
Documentation (h42techdoc.pdf, in the Documents folder), especially
portions of Appendix A (especially "Other Troubleshooting" and "General
Information") and Appendix D.1.

4) At this point, you need to compile the files to make an executable.
This may be done as described in the Hydrolight Technical Manual - see
Appendix A "General Information" section. What you need to do is to open
a windows command prompt (or dos command prompt) window. Change drives
to the drive where the Hydrolight directory lives on. Change directories
to the Hydrolight's maincode directory. Follow the compilation
instructions given in Appendix A. This creates an executable known as
maincode.exe.

Then change to the Hydrolight run directory. Then you need to issue the
following command:
..\maincode\maincode.exe < .\batch\Iroot.txt
but instead of "Iroot.txt" use the name of the input file that you want
to use, which usually exists in the HL's run\batch folder.

Good luck,

-M
