Thanks!

There are lots of free resources for Delphi newbies on the net + a very good
context sensitive online help. The description you requested is only a
keystroke away (for those who have Delphi installed.)
The Delphi help system is fantastic when you want to know for example what
ReadString does, but you can search for hours if you want to know the names
of the functions that you access ini-files with... Another quite fresh
example is the DecimalSeparator variable. I couldn't find it when I didn't
know what word to look for, but now I know thanks to Gary Williams and/or
Anders Isaksson.
I wish to focus on the difficulties LDraw related programming presents. I
will likely point to some good generic Delphi programming resources in the
coming foreword.

Yes, you're absolutely right. I even had it there, but removed it when I saw
a harmlesss but annoying bug that I wish to exterminate before publishing
that piece of code.

More comments will come.
Thanks for the input,
