[MIT-Scheme-users] floating-vector-ref? prmpnt.scm

[Scott Ballantyne]

I've been trying to load the prmpnt.scm file into 7.7.1 so I can
play with the picture language from SCIP, but I get an error:

1 ]=> (load "psgo")
 
;Loading "psgo.scm"
;Loading "prmpnt.com" -- done
;Unbound variable: floating-vector-ref
 
I am afraid I don't know how to fix this. Could someone pass me a clue?

Thanks a lot,
Scott
