Chapter 4 Transact Registers The Transact language differs from many conventional languages (such as COBOL and Pascal) in its use of dynamic, run-time "registers" to allocate and store data, control run-time processing, and communicate run-time status. Because these registers are active when the program is executing, you should always be aware of their values. Skillful manipulation of these registers can greatly improve both program and programmer efficiency. This chapter describes the Transact registers and how they work, including: * List and data registers * Key and argument registers * Match register * Update register * Input register * Status register
