void dal_mas_set_dal_fld_map (flg)

Sets the access mechanism for mask fields.

Input Parameters Significance
DtvLong flg 0 = linked lists
1 = MAP-mechanism
>=2 = hashmap mechanism

Output Parameters Significance
none -

Return Code Significance
none -

The access mechanism is usually defined by the default variable DTV_FLD_MAP_QUE in the repository. When the data structure is initialized via dal_dfv_ini, the local value will be set accordingly.

The selection of the access mechanism is only made when the mask is created. For existing masks changes to the flag are insignificant.

Note! The hashmap mechanism can only be applied if the epshr library exists and is found by DataView. If the library is unavailable, the MAP mechanism will be used automatically. Access via linked lists can only be reactivated by explicitly setting 0.
