Implementation
Link types will provide interfaces through the Link Support Entry Table (LSET) which is named in the linktype definition.
A LSET is not compatible with a DSET.
The device support layers Soft Channel and Raw Soft Channel will still be needed for each record type.
- A separate layer will be needed for each link type, although the amount of unique code required should be minimal.
The LSET address will be stored within the link field structure.
The same LSET can be used for DBF_INLINK, DBF_OUTLINK and DBF_FWDLINK types provided the relevant table entries are given.
Some existing db...Link and recGbl...Link routines could become macros for maximum performance.
