Hi,

My first question, so please bear with me... ;)

Does anyone know of a way to make case statements accept some construction of this kind:

case SomeInt of
  <10: DoSomething;
  10..1000: DoSomethingElse;
  >1000 DoSomethingDifferent;
end;

Yes, I can take a very high/low value for SomeInt (higher/lower than the highest/lowest expected value), like...

case SomeInt of
  -1000000..10: DoSomething;

...or even -2147483647, just to be sure :), and it will work, but it doesn't look/feel right.

BTW, I use D7 Pro.

Thanks!

Hi,

Not possible using case statement. Another way is using if statements but you already know that, right?

if SomeInt < 10 then begin
  DoSomething;
end else begin
  if SomeInt >1000 then begin
    DoSomethingDifferent;
  end else begin
    DoSomethingElse;
  end;
end;

Regards, Geo

hmm, kindof. you could use maxint

case SomeInt of
  10..1000: DoSomethingElse;
  1001..maxint: DoSomethingDifferent;
  else (*anything else is therefore < 10*) DoSomething
end;

@ geobul:
Yes, I know about if statments (frantically nesting ifs was my first passion when I started coding :), but as I hadn't explicitly ruled out this solution, your hint is valid and so I increased the points, in order to be able to split them (I hope it's ok to do it...)

@TheRealLoki :
Even if it's the same thing "under the hood", it sure is a big improvement. It definitely looks nicer than typing huge numbers.
I didn't know about maxInt (hmm, coming to think of it, I could have declared such a constant myself...).
And now I see there are many of them already declared: "MinDouble", "MaxExtended"...

Thanks!
