[fpc-pascal]Getting the size of an array

2003-10-02 Thread Andy Sy
In Delphi (the later versions I suppose), it is
possible to get the size of an array, and not just
the size of a String, using Length()
Is this not available yet in FreePascal or is there
another way of doing it?
You can use SizeOf, but then you'd have to get the
SizeOf the type of the array first (is this possible?)
and divide the SizeOf the array type by it.

[fpc-pascal]No runtime range checking?

2003-10-02 Thread Andy Sy
program blah;

type
  stringy = array[4..10] of char;
var
  C: stringy;
  D: array[2..5] of char;
procedure showstring(I:Integer);
begin
  Write(C[I]);
end;
begin
  C:='ABCDEFGHIJKLMNOPQRSTUVWXYZ';
  D:='ABCDEFGHIJKLMNOPQRSTUVWXYZ';
  Writeln(D);
  showstring(-5);
end.
FPC doesn't even complain about range exceeded whether
during compilation or runtime... isn't this an egregious
violation of Pascal's strict typing philosophy?  Does
Turbo Pascal/Delphi behave this way as well?

It is already supported in the development (1.1) compiler

Ah... turns out there's -Cr... I guess one can consider
it a debug on/off option.  Very nifty.  Just perfect.

It does:

Delphi doesn't compile your program:

[fpc-pascal]An 'all debug options enabled' command line switch

Might be a good idea to be able to compact

-Cr -Co -CR -Ct -Ci

into a single switch? -Cdebug or something like
that

You can combine it like this:

Hmm...  answering my own question... I guess -CritoR
is easy enough to remember... it should work
like -v, right?

I suppose this is because I'm assigning a larger string
to an array[] of char that cannot hold it.  Strange, even
with runtime range checking on, fpc doesn't catch this
problem.  dcc apparently does as early as compile time...
or am I missing something here?
Also, will the writing outside of array bounds in lines 16
and 17 corrupt memory even with runtime range checking on?
With RRC off, I'm almost sure it will, correct?

[fpc-pascal]switch suboption usage

2003-10-02 Thread Andy Sy
fpc accepts -glc, but will it work?  Or does one need to do -gl -gc?

For the help screen, what does the  after the switch invocation
actually mean?  You have multiple -g, -a, -s and -i suboptions, but they
are not indicated as -g, -a, -s and -i.
Also, how does one figure out from the help screen when bunching together
suboptions (i.e. -CritoR) will work and when they won't?
