README
^^^^^^
hello.pas
This is a sample "Hello, World!" Pascal Program
hello.pex
This is the compiled, linked P-Code executable that results
when hello.pas is compiled.
hello.h
This file defines an initialized C array holds a copy of
hello.pex. This file as created by:
xxd -i hello.pex >hello.h
mkhello.sh
This is a scripts that can be used to rebuild both hello.pex
and hello.h.
device.c
The hello.pex file must be provided to the interpreter as a file
in the file system. Normally this would be done using real storage
medium. In this example, we will use device.c:
device.c implements a simple device driver. Reads from this device
will access the in-memory copy of hello.pex This device driver is
registered as /dev/pashello in the psuedo filesystem.
