In reply to Aurelian_from_AMIQ:
Aurelian,
The format of the .ini file is very simple and was defined for Microsoft Windows a long time ago. With an awk/perl/< insert_your_favorite_scripting_tool_here > script, it should be very simple to modify the modelsim.ini file to meet your needs.
This forum is not the best place to get help with specific tool support. You should contact Mentor support directly if you need more help.
