The lnkConst.c implementation is not yet complete, no support for arrays of
strings (JMOP).
Link error messages should display their record & field name, which is not yet
possible.
The ability to embed links as parameters to other link types is not complete
yet; this will be required for the calc link type.
This code currently passes all existing tests, but additional tests are needed
for the new functionality.
