There is a bug in the rand function on 1.2, it returns negative numbers
which is at odds with the adobe standard, how ever it is easy to fix.
just add an value = labs(value); inside the rand function before
pushing the value back on the stack.. This can cause a lot of mysterious
"rangechecks" in sample files of the "draw random things on the page"
nature.. About the tracking of operator names.. An approach That I used
in my own postscript interpreter is not to place the address of the operator
into the operator object , but the index number of a look up table
for "name", "address" pairs, backtracking an operator becomes a simple case
of looking up the table and retrieving the name... 
This also allows one to have a central name/object table with a single install
 routine.
