/* RENUM [newLine],[oldLine],[step] */
By default, the whole program is renumbered starting at line 10 with multiples of ten.
It is important to note that ''jumps'' (<tt>GOTO</tt>, <tt>GOSUB</tt> and the like) are automatically converted to the new line numbers.
The whole set of parameters can be used to renumber only the last part of a program.
