Perfect? no. Better than leading 0? yes.
Leading zeroes that have meaning are an artificial construct. Keep in mind
that C users might be aware of deviant use (they are octal numbers as
literals), but Pascal users most probably wouldn't think twice.

It's a formatting string, not a number only. You think a digit *after*
the decimal point to be used for integers in front of the whole number
is more intuitive ?

With a C mindset, yes. There a leading 0 can have meaning. In Pascal an
extra leading zero never has meaning.

Yeah. Ah well, maybe in C07 that will be fixed.

As if format strings were intuitive at all. :-)
I'd call "Zero_Pad (Some_Int, 4)" definitely more intuitive.

Apart from the fact, that you can get run time type checking? Yeah, I
suppose so.

Well, let's assume it's due to Delphi-compatibility. Probably Borland
decided to do it differently just for the fun of it. ;-)

[fpc-devel] I can not build Lazarus with gtk2
I was compiling Lazarus with gtk2 (I have gtk2.8.17) in Linux and I got the following errors when linking: -=== /usr/lib/fpc/2.1.1/units/i386-linux/gtk2/gtk2.o: In function `GTK2_GTK_TYPE_FILE_CHOOSER_DEFAULT$$LONGWORD': gtk2.pas:(.text+0xb9b1): undefined reference to `_gtk_file_chooser_default_get_type' /usr/lib/fpc/2.1.1/units/i386-linux/gtk2/gtk2.o: In function `GTK2_GTK_TYPE_FILE_CHOOSER_EMBED$$LONGWORD': gtk2.pas:(.text+0xba11): undefined reference to `_gtk_file_chooser_embed_get_type' /usr/lib/fpc/2.1.1/units/i386-linux/gtk2/gtk2.o: In function `GTK2_GTK_TYPE_FILE_CHOOSER_ENTRY$$LONGWORD': gtk2.pas:(.text+0xba91): undefined reference to `_gtk_file_chooser_entry_get_type' lazarus.pp(113,1) Error: Error while linking make[2]: *** [lazarus] Error 1 TMessagesView.CollectLineParts WARNING: 20<>13 SrcLine=make[2]: *** [lazarus] Error 1 TExternalToolList.Run Exception: make[2]: *** [lazarus] Error 1 === I did look further and I found that I did not have the following files in my /usr/include directory: gtkfilechooserembed.h gtkfilechooserentry.h gtkfilechooserdefault.h The only place I have them is in my "/src/debug/gtk+-2.8.18/gtk/" directory. I suspect that gtk2 does NOT expose those functions at all.

Sounds like I found a case where 'C' is more intuitive than pascal ;-).
Seriously, isn't "Format" an imitation of C's printf ? At least they are
very similar, but on this detail (and maybe some others as well) they
are different.

I did read that page, but only saw 'padded with spaces' and assumed Precision was only applicable to floating point values, as it's "after the dot".
