Its really easy to add new functions to rlib...

put an entry into the rlib_pcode_verbs table in pcode.c
you also need to add a OP code define in pcode.h

then you implement the function (that you gave a pointer to in the
rlib_pcode verbs) in pcode_op_functions.c

It would be a 5 minute exercise if you want to try it

hint: just copy the "stod" operator... just don't pop any value off
RLIB's stack.. just push on a date...

I would call it "date"
