SELECTIVELY MODIFIABLE PHRASE STORAGE FOR A TYPEWRITER Abstract Printing operation sequences (e.g. code sequences representing phases of text) entered along with identifier codes by means of typewriter keyboard are stored for selective individual retrieval and may be replaced on an individual basis as the needs of the typewriter operator may dictate. By using a special end loading procedure for adding new sequences, both storage overlapping and build-ups of unused storage locations between sequences are avoided so that storage integrity is maintained while storage usage remains, nonetheless, efficient. In a preferred implementation, individual sequence retrieval capabilityis achieved by including in the respective sequences a common delimiter code along with a sequence identifier code. During bulk code transfers that occur when changes are made to the stored sequences, such delimiter and identifier codes are shifted routinely without being distinguished from the sequences they separate.
