[DUG] Count

[Jeremy Coulter]

SORT of along these lines, the other day I was altering a function in a 
Kylix app that i have written.
Well, I am using CrossKylix, but I think this is still usign the Kylix 
compiler.

Anyway, I was going :-

var
iVersion : double;
begin
if iVersion >= 1.4 then
blah
else
blah blah;
end;
Ok, thats fine, EXCEPT  "iVersion >=1.4"  was never true when iVersion was 
1.5 !!
In the end, I had to define another variable which was also a double (single 
and real had no affect either) then assigne 1.4 ti the new variable, THEN 
when I did iVersion >= iNewVar it worked.
Thats GOT to be a compiler issue. It def. compiles in the code example 
above, it just didnt evaluate properly....weired....and quite frustrating !
