' a) only "<<" and ">>" doesnt work (double quotation mark)
' b) and "namespace" doesnt know how to use, as function ?
' include <iostream>
' using namespace std;
int main {
const int myAge = 35;
'cout << "I am " << myAge <<
cout "I am "; '\n
cout myAge " years old ";
'cout str(myAge) " years old "; ' this line works too
return 0
}
' output 35 ' ok :-)
' changed oxygen.dll for it, see zip folder
