[fpc-pascal] format string - number padding

[ik]

Hello,

I'm trying to use the Format function to pad a number like so:
01
where the original value is "$1".

I tried to do the following:

writeln(Format('%02X', [$1]));
writeln(Format('%0:2X', [$1]));
writeln(Format('%:2X', [$1]));

All of them created the following output:
" 1"

What am I doing wrong ?

Thanks,
Ido
