PRODOS programming question

[SPA@NCCIBM1.BITNET (Jim Spath 410-631-3318, MD Dept of Environment.2500 Broening Hwy.Balt MD 21224-6612)]

I have compiled an Apple //e emulator program (ap2e) on a UNIX system,
and need to get some details about ProDos file i/o.  There were hooks
in the source code to allow for copying of the emulated Apple memory
out to a UNIX file, but no source code to do this.  In order for the
emulator to be of much use, I need to copy files.  Can someone point
me to the appropriate ProDos technical note that explains how to read
the disk directory, and bring sections of a file into specific places
in memory?  The ProDos manual that I have is non-technical, telling
me what my options are in the "FILER," nothing about how to do any
programming.

Sorry for not posting this in alt.emulators.ibmpc.apple2, but this is
a wierd conglomeration of events: a question about a system running
NetBSD UNIX on a PC clone, running an Apple emulator, being posted
through an IBM mainframe :-} .

Thanks.   Jim Spath <SPA@NCCIBM1.BITNET>
