 The following CFG evaluates to all possible syntactical correct "programs" (new & not yet public version):
-  START -> ASSIGN [COMMENT] '\n' START | ASSIGN [COMMENT]
+ START -> ASSIGN [COMMENT] '\n' START | ASSIGN [COMMENT]
-  START -> [COMMENT|COMMENTBLOCK] '\n' START | [COMMENT|COMMENTBLOCK] '\n'
+ START -> [COMMENT|COMMENTBLOCK] '\n' START | [COMMENT|COMMENTBLOCK] '\n'
-  ASSIGN -> (NAME ':=' )+ EXPRLST | NAME'(' [NAME (, NAME)* ] ')'
+ ASSIGN -> (NAME ':=' )+ EXPRLST | NAME'(' [NAME (, NAME)* ] ')'
-  EXPRLST -> [COMMENTBLOCK] (EXPR EXPRLST | EXPR) [COMMENTBLOCK]
+ EXPRLST -> [COMMENTBLOCK] (EXPR EXPRLST | EXPR) [COMMENTBLOCK]
-  EXPR -> FIRSTAVAIL | IFTHENELSE | FUNCTION | VARIABLE | STRING
+ EXPR -> FIRSTAVAIL | IFTHENELSE | FUNCTION | VARIABLE | STRING
-  FIRSTAVAIL -> '[' EXPRLST ( ',' EXPRLST )* ']'
+ FIRSTAVAIL -> '[' EXPRLST ( ',' EXPRLST )* ']'
-  IFTHENELSE -> '{' EXPRLST '=' EXPRLST '?' EXPRLST ':' EXPRLST '}'
+ IFTHENELSE -> '{' EXPRLST '=' EXPRLST '?' EXPRLST ':' EXPRLST '}'
-  FUNCTION -> '$'NAME'(' EXPRLST ( ',' EXPRLST )* ')'
+ FUNCTION -> '$'NAME'(' EXPRLST ( ',' EXPRLST )* ')'
-  VARIABLE -> '%'NAME'%'
+ VARIABLE -> '%'NAME'%'
-  STRING -> ('"'<Any string except ">'"') | ("'" <Any string except '> "'")
+ STRING -> ('"'<Any string except ">'"') | ("'" <Any string except '> "'")
-  NAME -> < Any String without the following characters := []'{}(),"%$? >
+ NAME -> < Any String without the following characters := []'{}(),"%$? >
-  COMMENT -> #< Any string >
+ COMMENT -> #< Any string >
-  COMMENTBLOCK -> /*< Any string >*/
+ COMMENTBLOCK -> /*< Any string >*/
