whoa! wow!! how about that! i'd have never thought to even try something like 
that... it looks the same as including environment variables in 4DOS/4OS2/4NT 
with the percents on both sides like that :) :) :)

i guess i'm going to have to figure out how to separate FPC from Lazarus so as 
to get a better base of FPC's offerings before attempting to dance the GUI 
dance... getting them in one package is nice except that one can get confused 
about what it available in Lazarus vs what is available in FPC...

i really do wish that the help files would come preinstalled in the available 
installation packages... installing on win and *nix leaves a lot to be desired 
as far as the built in F1 help stuff goes... especially when one has to go in 
and fill in the blanks with some unknown directory value(s) that are not readily 
apparent :? i won't even mention having a PDF of the documentation as i know 
that there's still work going on for the german language book that i hope will 
be released in english before too long...

thanks for sharing that :) if it were only that easy to grab other values like 
the compilation version number originally spoken of in this thread ;)
