This language can be extended when components are well designed. By the introduction of a data type conversion function in the edge design and can-connect function in input terminal, the extended data flow language successfully solved the data conversion between different data types. It is a difficult problem in data flow language to realize conditional jump and recursion, however, by using the mechanism of active condition, this dissertation solves the problem well.
