Abstract
Abstract A terminal apparatus for handling data by the field. Each field comprises a field defining character for defining an attribute of the field and a certain number of field data following the character. Information for determining the meaning of the field defining character is retained in the terminal apparatus and the attribute of the field is determined by the combination of the information and the field defining character. As a result, many field attributes can be specified.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
82 words
A terminal apparatus for handling data by the field comprising a series of data, comprising: first means for storing data including a field defining character located at a leading area of the field for defining the field; second means for retaining information for determining the meaning of said field defining character; and third means connected to said first and second means for determining the attribute of said field based on said information retained in said second means and said field defining character.
Claim 2
Dependent Claim
82 words
A terminal apparatus for handling data by the field comprising a series of data, comprising: first means for storing data including a field defining character located at a leading area of the field for defining the field; second means for retaining information for determining the meaning of said field defining character; and third means connected to said first and second means for determining the attribute of said field based on said information retained in said second means and said field defining character.
Claim 3
Dependent Claim
15 words
A terminal apparatus according to claim 1, wherein said third means includes microprogram control means.
Claim 4
Dependent Claim
121 words
a terminal apparatus having at least an output unit capable of visual output of fields of data, the mode of the output being determined for each individual field of data, the apparatus comprising: first storage means for storing therein at least a field defining character for defining each of the fields of data; second storage means for storing thereon information for use in combination with said field defining character to provide a modified definition of each of said fields of data; and processing means coupled to said first and second storage means to receive therefrom said field defining character and said information for formulating said modified definition for each of said fields of data, thereby determining said mode of the output.
Claim 5
Dependent Claim
121 words
a terminal apparatus having at least an output unit capable of visual output of fields of data, the mode of the output being determined for each individual field of data, the apparatus comprising: first storage means for storing therein at least a field defining character for defining each of the fields of data; second storage means for storing thereon information for use in combination with said field defining character to provide a modified definition of each of said fields of data; and processing means coupled to said first and second storage means to receive therefrom said field defining character and said information for formulating said modified definition for each of said fields of data, thereby determining said mode of the output.
Claim 6
Dependent Claim
25 words
An apparatus according to claim 3, in which said first storage means has memory areas for storing said field defining character and data corresponding thereto.
Claim 7
Dependent Claim
44 words
An apparatus according to claim 3, and further including a supervisory unit connected to said first and second storage means, said field defining character and said information to be stored in said first and second storage means, respectively, being applied from said supervisory unit.
Claim 8
Dependent Claim
129 words
A terminal apparatus having at least a display unit for displaying data, comprising: first storage means for storing therein a field defining character in a multi-bit format for each individual field, said field defining character serving to determine the mode of output of said data in terms of the binary states "1" and "0" of each of the bits of said field defining character; second storage means for storing therein control information serving to modify the meaning of at least one of the bits of said field defining character; and microprocessor means coupled to said first and second storage means for modifying the meaning of at least one of the bits of said field defining character in dependence upon said control information read out from said second storage means.
Claim 9
Dependent Claim
129 words
A terminal apparatus having at least a display unit for displaying data, comprising: first storage means for storing therein a field defining character in a multi-bit format for each individual field, said field defining character serving to determine the mode of output of said data in terms of the binary states "1" and "0" of each of the bits of said field defining character; second storage means for storing therein control information serving to modify the meaning of at least one of the bits of said field defining character; and microprocessor means coupled to said first and second storage means for modifying the meaning of at least one of the bits of said field defining character in dependence upon said control information read out from said second storage means.
