Thank you Rene,

I'm using bash.

I tried escaping the brackets, as per another private message:
CDEF:prec=PREV\(pippo\) \

but now it complains:

ERROR: rpn expressions without DEF or CDEF variables are not supported

and I think this happens next line:

     CDEF:time=TIME \

Any help appreciated
