Giving directly\opprint{var} is ineffective since this macro is a complexa gives side effect. It is necessary to access directly to this number.When a variable hold a number, xlop creates a macro \Op@var which containthis number. Note the uppercase “O” and the lowercase “p”. The atsign is here to do this definition a private one, that is, you have to encloseit with \makeatletter and \makeatother to access it (or \catcode @=11in TEX).1234× 56= 69104source\opcopy{1234}{a}\opcopy{56}{b}%\opmul*{a}{b}{r}%\makeatletter\newcolumntype{.}{D{.}{.}{­1}}\begin{tabular}{l.}& \Op@a \\$\times$ & \Op@b \\$=$ & \Op@r\end{tabular}\makeatotherNote that this way of doing don’t work when decimal separator is betweenbraces since macro \opprint{var} contain such braces. In thiscase, the simplest is to use \opexport macro (see page 25).45
