How To Transfer Machine Lang Executable From PC to A2?

[apple2ebeige@yahoo.com (Dave)]

I have a binary file that's a machine language executable for ProDOS
on my PC that I need to get onto the A2.  I have several comms
programs (zlink, proterm, etc.) that will transfer files, but there
seems to be some magic involved in making sure the resulting ProDOS
file is the right type.  Can anyone help out?

Also, is there an easy way to transfer a file from native file system
(PC, Mac) to an emulator disk image?

Thanks.
