Martin,

  Your problem would seem to be the line

        /MathGreek /Symbol /EFF_SymbolEnc FF

  It should be 

        /MathGreek /Symbol EFF_SymbolEnc FF

  What you have written puts a literal (the name if you like) on the stack
where the FF procedure expects to find an array (the value if you like). 
The copy operator is being used to copy the values from an array, in this
case one of the encodings, into THE encoding array of the font being
created.  If it meets a literal and an array it is bound to give a typecheck
error.

  Bruce.
