Hi,
C++Builder has a C++ template class named 'Set' to
emulate the Delphi set.
Look the help for 'Set'.

Here is an example:

//define a special Set for upper case  chars
typedef Set<char, 'A', 'Z'> CharSet;

CharSet mySet;
//mySet initially empty, fill with values
mySet << 'A' << 'B' << 'C' ...

char c = 'C'; //test

//this corresponds to Delphis 'in'
if(mySet.Contains(c))
   ShowMessage("Contains c");


Your code looks like you would never have to change
the set, though. In this case I would simply compare
against the upper and lower bound:

if(c > 'A' && c < 'Z')
   ShowMessage("Between A and Z");

Nick
