Gets the symbology ID of the specified field.
There may be more than one symbology ID in a field; pass in the zero-based Symbology Index. For example, Symbology Index 0 gets the first symbology ID. The return ID ANY means Use All Symbologies. An empty or blank return ID means either the filed has no symbology IDs or the field index is not valid.Use Get_Num_Field_Symbology_Ids to determine the number of symbologies for a field. This action is only valid when using IBM 5250 or 5555 emulation.
Scanner symbology values can be found in Symbologies and Values.
