[pstricks] postscript calculation within pstricks arguments

Hi, I have the following:





       \rput[cc]{!4 \I\space mul 4 \i\space mul add}(!1 dup \i\space mul 
5.2 sub exch \I\space sub 2.7 add){%

but I would like to perform postscript calculations as follows (for 
instance) :

\mypsframe{\i}{\I\space \i add 10 mul}

but it does not work. Is there a systematic method for such requests?

Thank you
