Hm, well, yes... Sending... ;-)
opencbm floppy modules:
The opencbm API (cbm4win, cbm4linux) will(*) use the o65 file format for
modules to load into floppy. The API itself loads o65 files to account
for the differences between the various floppy drives (1540/1541,
1570/1571, 1581), and to present the API user transfer protocols for its
use. The API user loads additional modules into the floppy drives which
then use late binding to connect to the various support routines of the
floppy ROM, or of the transfer protocols. Name encoding is ASCII, name
length are restricted to 1024 characters currently (will be removed most
probably in the near future). Currently, the simple file format is not
required (but there is no definitive decision about this yet).
Currently, o65 files for the opencbm API are restricted to a total of
64KB (65536 byte) in length.
(*) remember: This is work in progress, so the details are subject to
change.

Sorry. This mail was not meant to be sent yet but I wanted to postpone
it. The @@@SRT mark is a sure indicator for this. ;-) It seems I pressed
the wrong keys.
I will have to look up again my source code to ask exactly about my
problems via PM.

Ok, this is good. Anyway, I might remove the restriction to 1024 byte
soon as I changed my file handling code in the meantime.
Regards,
Spiro.
