NOLAXQUAL(FULL)

Specifying NOLAXQUAL(FULL) causes the compiler to flag any reference to structure members that do not include the the full qualified name. Consider the following example:
dcl
1 a,
2 b,
3 b fixed bin,
3 c fixed bin;

c = 11; /* would be flagged */
b.c = 13; /* would be flagged */
a.c = 17; /* would be flagged */
a.b.c = 42; /* would not be flagged */

    I thought about examples like this:

    dcl 1 struc
    ,2 part1
    ,%include COPYB1
    ,2 part2
    ,%include COPYB2
    ;

    struc.value = 42; //Ex1
    struc.part1.value = 42; //Ex2

    If you have to maintain such nested include structures you know in Ex2 exactly where you have to search but in Ex1 you have to search in every include to find that field.
    Sure, a global NOLAXQUAL(FULL) my not always be the best idea but if you may can use it with a FORCE-statement it would be much more useful.

    This is easy to implement in the compiler, but it might indeed be quite unpopular with developers

    From the poster:

    > This enhance will force the developer to always use just full qualified structure name.

    This will make your developers hate you like the plague. Have you ever programmed in Pascal, where, unless you use the very dangerous "with" statement, you have such abominations as "MyStruct.ThisPart.LowerLevel.Field.DatapointX.DatapointY.Centre" Forcing the same onto your developers will significantly lower their productivity, and is likely to increase the number of typos significantly.
