Abstract
Abstract A system for use in a keypunch application. Keyed data is recorded onto a magnetic card. To prevent interruption of the keying rhythm during movement of the read-record head from track to track and during card feed, a two-sectioned memory is employed, which through selection of a single address and gated logic allows data to be transferred from one section to the other section without need of buffering or other types of temporary storage or delay. The two-sectioned single address memory is also utilized during verify and duplication operations with, in the case of the latter, the data from a first record being entered from the keyboard into the first section of memory and being transferred to the second section for transfer to the magnetic card. During duplication into a second record from the keyboard, data is transferred back into the first section from the second section through utilization of the single address technique.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
109 words
A data processing system wherein records of data and control functions are keyed into a keyboard which provides coded indicia of the keyed data and control functions, said system comprising: first and second temporary storage means, means for entering said coded indicia records into said first temporary storage means from said keyboard, means for transferring said records from said first temporary storage means to said second temporary storage means, a magnetic card read-recorder operative to record said records on a magnetic card and read records therefrom, and means for transferring said records from said second temporary storage means to said magnetic card read-recorder for recording on said magnetic card.
Claim 2
Dependent Claim
109 words
A data processing system wherein records of data and control functions are keyed into a keyboard which provides coded indicia of the keyed data and control functions, said system comprising: first and second temporary storage means, means for entering said coded indicia records into said first temporary storage means from said keyboard, means for transferring said records from said first temporary storage means to said second temporary storage means, a magnetic card read-recorder operative to record said records on a magnetic card and read records therefrom, and means for transferring said records from said second temporary storage means to said magnetic card read-recorder for recording on said magnetic card.
Claim 3
Dependent Claim
42 words
The system of claim 1 wherein said means for transferring records from said first temporary storage means to said second temporary storage means includes a single address decoder and transfer gating means operative during a single memory cycle to effect said transfer.
Claim 4
Dependent Claim
25 words
The system of claim 2 wherein said first temporary storage means is cleared for accepting new keyed data upon the completion of a keyed record.
Claim 5
Dependent Claim
44 words
The system of claim 3 further including means for transferring portions of said records contained in said second temporary storage means to said first temporary storage means during a single memory cycle under control of said single address decoder and said transfer gating means.
Claim 6
Dependent Claim
50 words
The system of claim 1 further including means for reading said records recorded on said magnetic card into said first temporary storage means, a single character register, and means for comparing verification data keyed into said single character register with data in said first temporary storage means character by character.
Claim 7
Dependent Claim
50 words
The system of claim 4 further including means for reading said records recorded on said magnetic card into said first temporary storage means, a single character register, and means for comparing verification data keyed into said single character register with data in said first temporary storage means character by character.
Claim 8
Dependent Claim
27 words
The system of claim 4 further including program storage means for storing therein program control codes operative to format data entered into said first temporary storage means.
Claim 9
Dependent Claim
48 words
The system of claim 7 wherein there is recorded in said program storage means a program control code for each character position in said first temporary storage means which said program control codes are sequentially called out from storage in one for one correspondence with said keyboard entries.
Claim 10
Dependent Claim
46 words
The system of claim 8 wherein there are a plurality of program levels each including a program control code for each character position in said first temporary storage means and said program levels can be selected from said keyboard or from said first temporary storage means.
Claim 11
Dependent Claim
88 words
A data processing method wherein records of data and control functions are keyed into a keyboard which provides coded indicia of the keyed data and control functions, said method comprising: recording a first coded indicia record into a first section of memory and upon the occurrence of an end of record transferring said first record into a second section of memory, and rEcording said first record from said second section of memory onto a magnetic card while a second record is keyed into said first section of memory.
Claim 12
Dependent Claim
88 words
A data processing method wherein records of data and control functions are keyed into a keyboard which provides coded indicia of the keyed data and control functions, said method comprising: recording a first coded indicia record into a first section of memory and upon the occurrence of an end of record transferring said first record into a second section of memory, and rEcording said first record from said second section of memory onto a magnetic card while a second record is keyed into said first section of memory.
Claim 13
Dependent Claim
45 words
The data processing method of claim 10 wherein transfer of records from said first section of memory to said second section of memory is accomplished in one memory cycle through use of a single address decoder and transfer logic connecting said two sections of memory.
Claim 14
Dependent Claim
62 words
The data processing method of claim 10 wherein only a portion of a record is keyed into said first section of memory and the remainder of said record is transferred from said second record to said first record and the complete record then transferred from said first section of memory to said second section of memory for recording on said magnetic card.
Claim 15
Dependent Claim
41 words
The data processing method of claim 12 wherein said transfer between said first and second sections of memory is accomplished in a single memory cycle through use of a single address decoder and transfer logic connecting said two sections of memory.
Claim 16
Dependent Claim
65 words
The data processing system of claim 10 wherein for data verification data to be verified is read from said magnetic card into said first section of memory and the verification data is entered one character at a time into a single character register and a character by character comparison made between said characters entered into said single character register and said data to be verified.
Claim 17
Dependent Claim
41 words
The data processing method of claim 14 wherein said transfer between said first and second sections of memory is accomplished in a single memory cycle through use of a single address decoder and transfer logic connecting said two sections of memory.
Claim 18
Dependent Claim
25 words
The data processing method of claim 15 wherein said data entered into said first temporary storage means is formatted in accordance with stored program codes.
