This doesn't look right to me?  The test is prefixed with

  .k02.array=3D(characters in an array)

${!.k02.ref} should not return "characters" ...?  That makes '!' just
a no-op for this case.

Test K02parameter.ztst failed: output differs from expected as shown above =

Was testing: namerefs with namespaces
