Abstract
A method and system providing switching between a plurality of installed programs in a computer system. Embodiments include a jump function comprising the steps: (1) determining a jump program that is to be the next program to be run, possibly from a plurality of possible choices; (2) creating input data for the jump program based on data in the current program; (3) storing the program state of the currently running program into a context packet and saving the context packet to memory; (4) releasing temporary memory that is used by the program, so as to allow other programs to use the memory; (5) calling the jump program with the created input data as input and terminating the currently running program.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
