<!--DONE:
	- comments are there
	- substitutions are there
	- basic variable function handling, distinguishing the function result between numerical and string
	- variables are there (somehow)
	- numbers will be found
	- escape characters are found and highlit
	- jumps, gosubs and labels
	- command grouping
	- conditions
	- redirection
	- many different command handlings
		- iff
		- echo
		- text/endtext
		- set/unset
		- input/inkey
		- do
		- for
		- switch
	- internal commands of 4DOS
	TODO:
	- if someone finds that PATH-detection makes sense: create it...
	- whatever doesn't seem to be correctly lit after all the preceeding stuff ...
	- follow the TODO-Marks
