B := StrToIntDef('100', 0); // string '100' converts to int 100
C := StrToIntDef(' -12', 0); // initial spaces are ignored
D := StrToIntDef('$1E', 0); // hex values started from '$'
E := StrToIntDef('-0x1E', 0); // ... or from '0x'
F := A + B + C + D + E; // add up all of these integers
mLogScript('A : ' + IntToStr(A), '');
mLogScript('B : ' + IntToStr(B), '');
mLogScript('C : ' + IntToStr(C), '');
mLogScript('D : ' + IntToStr(D), '');
mLogScript('E : ' + IntToStr(E), '');
