Abstract
Abstract A method of on-line reconfiguring a data processing system for an added input/output (I/O) device in which a configuration program is called and menus are presented. Based on menu selections, the program causes a device definition to be built. The built definition is used to construct a control block which is stored into main storage during system operation such that the added device is available for use on a real time basis.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
95 words
A method of on-line reconfiguring a data processing system including a keyboard and a display for an added device comprising calling a configuration program which causes menus to be presented on said display ; said method being characterized in that it comprises the steps of - building a definition for said device based on keying on said keyboard and menu selection - determining a status of said defined device; and - building and storing a control block in main storage for said system based on said status and said definition during operation of said system.
Claim 2
Independent Claim
95 words
A method of on-line reconfiguring a data processing system including a keyboard and a display for an added device comprising calling a configuration program which causes menus to be presented on said display ; said method being characterized in that it comprises the steps of - building a definition for said device based on keying on said keyboard and menu selection - determining a status of said defined device; and - building and storing a control block in main storage for said system based on said status and said definition during operation of said system.
Claim 3
Dependent Claim
29 words
A method according to Claim 1 including, if said defined device has a status as a new device to said system, adding said control block to said main storage.
Claim 4
Dependent Claim
50 words
A method according to Claim 2 including, if said defined device has a status as a redefined device, building a redefined control block based on said device definition and replacing a control block for a device being redefined if said device being redefined has a status of not in use.
Claim 5
Dependent Claim
32 words
A method according to Claim 3 including replacing said control block for said device being redefined by deleting said control block for said device being redefined and adding said redefined control block.
Claim 6
Dependent Claim
32 words
A method according to Claim 3 including replacing said control block for said device being redefined by writing over said control block for said device being redefined with said redefined control block.
Claim 7
Dependent Claim
32 words
A method according to Claim 3 including writing said redefined control block behind said control block for said device being redefined if said device being redefined has a status of being used.
Claim 8
Dependent Claim
17 words
A method according to Claim 6 including marking said device control block for said device being redefined.
Claim 9
Dependent Claim
31 words
A method according to Claim 7 including deleting said device control block for said device being redefined when said device being redefined has a status of being no longer in use.
Claim 10
Dependent Claim
19 words
A method according to Claim 8 including storing said device definition in a secondary store such as a disk.
Claim 11
Dependent Claim
25 words
A method according to Claim 9 including updating said secondary store to include an updated catalog of definitions of devices in use by said system.
