ABSTRACT:
An editing system for processing the contents of a random access memory, used in conjunction with a visual display and an alphanumeric control keyboard. The editing system comprises two basic sequential circuits which permit either the deletion of a character or insertion of a character within the memory. A void created by the deletion of a character will be removed simply by reorganizing the memory following the deletion. Conversely, characters may be inserted within the contents of the memory at any desired memory location without destroying the contents of memory at such location by reorganizing the data following the point of insertion. Further use of the insert and delete sequence logic is employed in a manner which automatically permits more complex operations to occur, as required by the operator, such as removal of multiples of characters or words or to further reorganize the memory contents.
