Toolhelp ruft diese Funktion, ohne das SS-Register aufs Datensegment

* Single-Instance-Application
- "mov ds,seg @data"
- "export" ist sinnlos, es genügt "far"; dann muß DS gerettet werden
* Multiple-Instance-Application
- Verwendung von MakeProcInstance() und FreeProcInstance() erforderlich
- $K- schalten oder (da dieser Schalter leider global ist)
- "export" durch "far" ersetzen und am Eintritt den Assemblerbefehl
"mov ds,ax" setzen. Nicht vergessen, DS zu retten}
