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.
