A technique is described whereby a software algorithm used in conjunction with microprocessors, such as an Intel 8085, will provide a multiple searching capability in a limited domain environment. Microprocessors with a limited instruction set, such as the Intel 8085, normally require an extensive use of code to provide a multiple search capability. The algorithm described herein optimizes the code so as to search for one item in a limited domain of items. It is more efficient than the standard scan field and increment routines usually used. An example of a use for this technique is in applications where identification of a character is required in a line-turnaround situation. Since comparisons are made in each receiver handler, the receiver handler is interrupt driven and is therefore time constrained.
