The *.kx file is a tokenised version of the original plaintext *.kix file.

It may well include CALLs to other scripts (which may or may not be tokenised themselves). These are read in at run time as the CALL statement is executed.

It may also originally have had INCLUDEs, which pull other files in at tokenisation time and create a monolithic stand-alone script.

Path information is not hard-coded into the kix32.exe intepreter.
