Function identifies a context (and connects to it), within which the functions %HI_EDADebugVectorRec or %HI_EDADebugCalcFunctionRec will debug EDA vector.

Function should be called before calling %HI_EDADebugVectorRec and %HI_EDADebugCalcFunctionRec to identify the existing connection between EDA Server and EDA Client. This connection is given just a pair of identifiers of EDS and EDC processes.
Parameters _EDA_hbj and _EDC_hbj may be get by calling the external function CALL %EDA_GetProcessID(INT out _EDS_hbj, _EDC_hbj, _retCode) (described in EDA System documentation). Function returns the identifiers of EDS and EDC processes, which are used by currently executed ESL script. The connection to EDA Server is necessary condition.
The connection will be closed after calling %HI_EDADebugClose.
