Commenting globals
Source comments can be added to symbols defined in a GLOBALS / END GLOBALS
block.
The global symbols included from an external file with GLOBALS
"filename" will not be part of the module documentation.
Example
GLOBALS
    #+ a global variable
    DEFINE globalVar1 INT
    #+ a global type
    TYPE GlobalType1 RECORD
        f1, f2 INT
    END RECORD
    #+ a global constant
    CONSTANT globalConst1 = 9999
END GLOBALS
