Hitachi Ltd has introduced a software development support environment for its 2050 Unix workstation under the name SEWB, which extends downwards the facilities of its Eagle software development support tool already offered on the M-series IBMulators: in in-house tests the environment is claimed to have doubled productivity, and reduced program errors by one third; it makes full use of graphic capabilities, using a graphic expression system instead of a flowchart to integrate the planning, programming and coding stages, and generates Cobol or C source programs; it consists of nine separately-priced programs at a typical $650 apiece.
