Improve how the move instruction with differing lengths is handled

There has been a lot of discussion on the assembler forum on issues with the MVC and differing length fields.
Sample macros have been added that help assist in this area. Many customers have home written macros.
Example statements include:
'Storage overlays where you specify the length greater than the receiving fields length can be much worse to diagnose'
'With the current MVC, it's all too easy to get garbage after the desired text. I've also seen horrors where all possible error texts have an explicit length, wasting more storage than needed.'
The issue of field lengths has also been commented in other instructions such as the compare instruction.
This RFE has been raised on behalf of the Assemble lists for IBM to see what can be done to improve this area of language.
(Comments on the list can be found if you search for: MVC2 Assembler list

    This requirement has been re-assessed by the current team. We understand the problem, but we feel that the suggested enhancements do not provide sufficient benefit to be worth the additional complexity, especially as specific cases can already be addressed by macro instructions. We are therefore declining this requirement.

    Due to processing by IBM, this request was reassigned to have the following updated attributes:
    Brand - Servers and Systems Software
    Product family - Enterprise Tooling
    Product - High Level Assembler (HLASM)

    For recording keeping, the previous attributes were:
    Brand - WebSphere
    Product family - Enterprise Tooling
    Product - High Level Assembler (HLASM)

    I accept the principal of improving this area. I would add that there may be challenges in changing the assembler to achieve a complete, better fix.
    It will be added to our candidate list

    This should not be limited to z/OS. Also: z/VSE and z/VM.
