HCR Corp, Toronto, Canada, and Associated Computer Experts BV, Amsterdam, are to merge their respective C compiler test suites into a new integrated version, and the first fruits of the agreement will be available from the third quarter. Customers who already have both separate compilers will be offered the jointly-developed C test suite for a reduced licence fee of $15,000. HCR is to sell the thing in North America, ACE in Europe and the Middle East – and elsewhere the two will work together. HCR is also to begin distribution of Unix-based Computer-aided software engineering tools developed by Deft Inc, Rexdale, Ontario, for Compaq Computer Deskpro 386 and Sun Microsystems Sun-3 machines. In addition HCR will itself develop the tools for IBM RTs and Sequent systems.
