on the surface, this would seem to be similar to the C style
preprocessor stuff that takes "macros" like __DATE__ and __TIME__ and
converts them to the current date and time and writes them into the
object code... i did something like this for TP6/BP6 way back in the
day... set those as consts in an include that was rewritten each time by
my preprocessor before the command line compiler was called... actually
using them (ie: forcing them to be included in the binary) required that
at least one const string be used in the execution of the program...
these didn't have to be used in the code but they were included such
that one could see them in the binary when it was viewed via a hex
editor/viewer...
Did you know about this:
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 ;)

program Foo;
{$apptype console}
begin
Writeln({$I %DATE%} + ' ' + {$ %TIME%});
Readln;
end.

It's documented here:
