Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
63 words
AN information processing device, including error processing apparatus comprising: means for monitoring a predetermined set of conditions in said information processing device; means, responsive to said means for monitoring, for detecting which one of a plurality of types of errors in said conditions exists, and means, responsive to said means for detecting, for indicating the procedure for correcting the said type of error.
Claim 2
Dependent Claim
63 words
AN information processing device, including error processing apparatus comprising: means for monitoring a predetermined set of conditions in said information processing device; means, responsive to said means for monitoring, for detecting which one of a plurality of types of errors in said conditions exists, and means, responsive to said means for detecting, for indicating the procedure for correcting the said type of error.
Claim 3
Dependent Claim
47 words

Claim 5
Dependent Claim
25 words
The device of claim 3 further comprising memory means for controlling said means for entering and said means for recording; and for storing said information.
Claim 6
Dependent Claim
36 words
The device of claim 4 in which said recording medium is a magnetic medium and said means for recording includes magnetic head means and means for driving said medium and head means relative to one another.
Claim 7
Dependent Claim
29 words
The device of claim 5 further including means responsive to said memory means for verifying in verify mode said information entered in entry mode by said means for entering.
Claim 8
Dependent Claim
34 words
The device of claim 6 in which said means for indicating is a display means for providing a visual indication of the occurrence of an error and the required procedure for correcting that error.
Claim 9
Dependent Claim
69 words
The device of claim 6 in which said conditions monitored include: parity values accompanying information processed in said device; miskeying of said keyboard; the size of units of information processed by said device; the mode of operation of said device; and differences between the information stored in said memory and in corresponding areas of said medium; and said means for monitoring includes means for sensing each of said conditions.
Claim 10
Dependent Claim
31 words
The device of claim 8 in which said means for detecting includes means, responsive to each of said means for sensing, for identifying an error as a particular type of error.
Claim 11
Dependent Claim
31 words

Claim 14
Independent Claim
56 words
A method for indicating errors in the operation of a keyboard operated digital data processing device comprising classifying error conditions into groups in accordance with recovery procedures for correcting the respective error conditions and providing displays each responsive to one of said groups of errors said displays indicating the procedures for recovering from said error conditions.
Claim 15
Independent Claim
56 words
A method for indicating errors in the operation of a keyboard operated digital data processing device comprising classifying error conditions into groups in accordance with recovery procedures for correcting the respective error conditions and providing displays each responsive to one of said groups of errors said displays indicating the procedures for recovering from said error conditions.
Claim 16
Dependent Claim
28 words
