I ran into a similar issue last week. I did find that R5RS mode has some of this functionality. It also has the useful 'system' procedure.

Subject: [Larceny-users] Request: string-port? predicate
Content-Type: text/plain; charset=US-ASCII
I would like to implement a function which returns the "contents" of a port as a string.
It would be useful to test an output-port to see if get-output-string can be applied.
[larceny in -r7rs bahaves:]

(import (primitives string-output-port?))
string-output-port?

...
message : "?: undefined global variable: string-output-port? \n"

(import (primitives string-port?))
string-port?

...
message : "?: undefined global variable: string-port? \n"
It would also be useful to know the byte-length of a file, and deal with directory and file entries..
Thanks much,
-KenD
