They decided to write the system in the C programming language, although Pascal was far more common on the Mac at that time. With the funding secured in the summer of 1985, Wulf hired two friends, Bob Murphy and Ken Clark, one from college and one from his previous job, to help him write the system. This resulted in the creation of Data Tailor. He offered to arrange funding for the development of the new product, in exchange for shares in a new company to write it. Wulf's office was a shared space, and one of the other groups included someone who was familiar with startups. This meant that the blocks could move and the formulas would still work. While considering this, Wulf hit upon the idea of "blocks", which would isolate inputs into separate named sections and the formulas could be applied to the names, not the cell references. While working on them, Wulf was constantly irritated by the way minor changes to the spreadsheet layout would cause the formulas to stop working. Their first products were a series of Multiplan spreadsheets for the oil and gas market, but these did not sell well. In 1984, after seeing the Macintosh computer, Andrew Wulf quit his job at a defence contractor and started a small consulting firm to work on microcomputers. This concept is also seen in the modern Apple Numbers. This basic concept of using separate blocks of data and their names to create formulas was the major feature of Lotus Improv, introduced in 1990. When DeltaPoint's DeltaGraph became a huge hit later that year, sales of Trapeze were ended. The company was purchased by a minicomputer software vendor as part of an effort to break into the microcomputer market, but they decided to exit the business and sold it off again to a new company, DeltaPoint, in 1989. Introduced in January 1987 at MacWorld San Francisco, sales were not strong and the company formed to introduce the product was insolvent by the fall. The system did not rely on the sheet as the basis for storage, and allowed multiple tables, charts, graphics and text, which they referred to as "blocks", to be positioned freely. This, in turn, made updating the sheets by moving data around a safe operation, whereas in contemporary programs like Microsoft Excel and Lotus 1-2-3 this often led to broken formulas. It introduced the concept of using named ranges for most operations instead of cell addresses, allowing formulas to be freed of the location of the data on the page. Trapeze is a discontinued spreadsheet program for Macintosh systems running classic Mac OS.
