Abstract:

Interactive use of the RAND TabletStylus and a CRT display demands that many independent data packages be accessed in real time without the mans being aware of system operational tasks. The internal representation of the mans program consists of its picture form, data structures to denote properties implied by the picture, and positional information to relate stylus location to the other forms. Dynamic storage allocation is automatically provided because of the large number of data sets. Algorithms are described which handle scheduling, priority, synchronization, and parallel processing. This is the third part of a final report on GRAIL.
