ABSTRACT:
A system for editing characters stored in a memory is provided with a maximum count register and address counter means. The data at the address in memory desigated by the address counter means is removed from memory and temporarily stored in an output register. Data in an input register is then transferred to said address in memory and the data in the output register is then supplied to the input register. The address counter means is counted one count and the sequence is repeated until the count in the maximum count register is equal to the count or address in the address counter means. A delete edit function is accomplished by decrementing the address counter means and an insert edit function is accomplished by incrementing the address counter means.
