The long string in/out records use a different initializer
for constant links. The new loadLS method allows a constant
link type to initialize such a long string field.
NB: This routine was added in the middle of the lset table.
Any external link support implementations must be adjusted.
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.
Both Perl and dbStaticLib support included.
Also added a new std/link directory for link types.
Nothing looks up the registered link support tables yet.
