I appreciate implementations where you cut than adding to it! 😊

In addition to my comments on specific files, it seems there's no test that follows this structure:

• Declare a DS1 with StringType, NumberType zoned, and NumberType packed.
• Declare S1, a standalone StringType similar to DS1.
• Declare DS2, structured like DS1.
• Assign DS1 to S1 and then assign S1 to DS2.
• Assert that each field of DS1 is equal to the corresponding field in DS2.

I have a doubt about a test

As I understand my changes to MUTE13_41 were not appropriate I rolled it back to the original version @benetti-smeup gave me and only added the MUTE assertions in it. Let me know if it ok now and else-wise what needs to be changed.
