UK software house Zortech Ltd of Woolwich, South London, claims it is the first company to come out with a full C compiler for the MS-DOS environment – C translators and code generators for MS-DOS, such as Glockenspiel’s designer C , have been around for some time – and the company says it shipped 3,000 copies in the first seven days since its launch last month. Zortech managing director John Haggins says that the Zortech product also includes a standard C compiler, so that programmers are able to make a gradual transition to object-oriented programming. The larger models are included allowing the compilation of programs up to 1Mb in size, and Haggins says that all the examples in the standard text on C by Bjarne Stroustrup have been compiled and tested. Zortech boasts a worldwide distributor network, and has already sold 250 copies in Sweden, and signed up software distributors MSA in Japan. In the US, Zortech has set up a subsidiary operation based in Boston, and is shipping the first copies there this week. Demand for C , says Haggins, is tremendous. The company is now working on an OS/2 version and a version optimised to run on the 80386 processor, promised in three months time. Zortech C is available on eight floppy disks, representing 2Mb code, and the cost in the UK ic UKP99.99 plus VAT: in the US it costs UKP149.
