[Gd-hackers] With-open-file in Open Dylan

[Gareth Baker]

Thanks for the hints - I can get it to work now.

General question - Other than wading through the library files, is there an
easy way to determine which library and module needs 'using'? For
'with-open-file' the old Harlequin Dylan/Open Dylan documentation  on the
web site seems to indicate that the library is 'io' and the module is
'streams'!

Anyway - thanks again
Gareth Baker
