An X/script source can be composed of one or more ASCII file sources, written without any particular format.

Each text line is separated from the next with CR+LF (or only CR according platform convetions).

Joining lines

For joining two consecutive lines, use symbolic \ as the last character.

Symbolic names

Characters allowed for symbolic names (functions, variables, labels, etc) are:

•all letters (X/script language is not case sensitive);

•all digits (excluding the first name character);

•characters _

The following characters are reserved by the language:

=   <   >   !   ~   .   +   -   *   /   ,   (   )   [   ]   “   $   ;   |   &   :   \  .

Comments

All characters followed by the ; symbol up to end of line are ignored by the compiler, so ; can be used to write comments inside the source code.
