I think Graeme's point was that if you have a good grasp of software design and programming techniques, you can write good software in whatever language you choose. I have seen this in practice, so I agree to an extent. Obviously the programming paradigm of the language you choose will have an influence, so the old saying of choosing the right tool holds.

[fpc-pascal] Division by Zero: EDivByZero and EZeroDivide
Hi,
Is there a reason why in fpc both floating point and integer division
by zero raise an EDivByZero exception?
See: http://docwiki.embarcadero.com/VCL/en/SysUtils.EZeroDivide
SysUtils.EZeroDivide exception is raised when an application attempts
to divide a floating-point value by zero.
Note: Integer divide-by-zero errors raise the SysUtils.EDivByZero exception.
program zerodiv;
{$IFDEF FPC}
{$mode objfpc}{$H+}
{$ENDIF}
uses Sysutils;
var r,x: extended;
i,j: integer;
begin
i := 0;
r := 0.0;
try
write('Integer division by zero: 1 div 0 - ');
j := 1 div i;
writeln(j);
except
on e: exception do writeln(e.classname);
end;
try
write('Float division by zero : 1.0 / 0.0 - ');
x := 1.0 / r;
writeln(x);
except
on e: exception do writeln(e.classname);
end;
end.
Output with Delphi (3.0:
Integer division by zero: 1 div 0 - EDivByZero
Float division by zero : 1.0 / 0.0 - EZeroDivide
Output with Fpc 2.2.4 (tested on win32 and Linux i386)
Integer division by zero: 1 div 0 - EDivByZero
Float division by zero : 1.0 / 0.0 - EDivByZero
Is this by design, or should I report it as a bug?
(B.t.w. setting mode to delphi makes no difference)
Bart

Re: [fpc-pascal] Who said Pascal isn't popular
A quick study of some language reference docs and a few examples should be all you need to get started. The general rules are easy to learn. But to be productive you also need to know about environments (IDE etc.), available libraries and their usage (which already differ between Delphi and Lazarus), bugs (and their workarounds) and OS dependencies and maybe even need to have lots of own code which you can reuse. So only getting the basics of a language is not enough IMO. And then it *does* matter whether you are used to program in a certain language (on a certain OS) or not. ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal

They do (sometimes at least). Still they write it as they would do in C. A quick study of some language reference docs and a few examples should be all you need to get started. A quick study of the language reference doesn't tell you why types suddenly are important. Why visibility isn't global anymore. Why modules are compilation units and not include files etc. pp. Those ideas can be totally new to a C-programmer. - And then they start moaning about the awkward syntax of begin and end... ;) Or, as the old saying is: One can write Fortran in any language.
