Re: [DUG] Val Function

[Steve Peacocke]

Use the Real value...
Function IsNumber(A:String):Boolean;
Var
  I: Real;
  j: Integer;
Begin
  Val(A,I,j);
  result:=j=0;
End;
This will give the correct result.

Why is that
IsNumber('A19')=FALSE
while
IsNumber('X19')=TRUE
Val function assumes 'X19' is Hexadecimal.
Can I force it to interpret the parameter as
string? Any clues?
