Abstract
Abstract A method and apparatus for transforming data transmitted from a remote information processing system which operates in a first internal code format to the internal code format of a second receiving information processing system. The method includes a control program for operating the receiving information processing system in an interactive mode with the operator. The control program displays prompts and command options to the operator which enables the operator to construct a transform table of conversion characters for the communication session. The conversion table is also useable by the control program routines to reverse the data transmission operation by converting the internal code format of the second information processing system to the internal code format of the first information processing system for data transmission in the opposite direction.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
250 words
In a data communication system including a first information processing system which operates on internal code of a first format and a second information processing system which operates on internal code of a second format different from said first format, an interactive control system for transforming the communicated code of said first information processing system to the format of the code of said second information processing system comprising: means connected to said second information processing system for displaying to an operator of the second information processing system a menu of code format transform tasks available for operator selection; means connected to said second information processing system and responding to the selection of one of said code format transform tasks by the operator for displaying a transform file of characters and control instructions of said first information processing system together with corresponding default characters and control instructions in the format of the second information processing system; means connected to said second information processing system and responding to the display of said transform file for selectively replacing certain ones of said default characters and control instructions in said transform file with characters and control instructions selected by the operator; and means connected to said second information processing system and responding to the replacement of said default characters and control instructions for merging said transform file into a transform program for transforming the communicated code of said first information processing system to the format of the code of said second information processing system.
Claim 2
Dependent Claim
250 words
In a data communication system including a first information processing system which operates on internal code of a first format and a second information processing system which operates on internal code of a second format different from said first format, an interactive control system for transforming the communicated code of said first information processing system to the format of the code of said second information processing system comprising: means connected to said second information processing system for displaying to an operator of the second information processing system a menu of code format transform tasks available for operator selection; means connected to said second information processing system and responding to the selection of one of said code format transform tasks by the operator for displaying a transform file of characters and control instructions of said first information processing system together with corresponding default characters and control instructions in the format of the second information processing system; means connected to said second information processing system and responding to the display of said transform file for selectively replacing certain ones of said default characters and control instructions in said transform file with characters and control instructions selected by the operator; and means connected to said second information processing system and responding to the replacement of said default characters and control instructions for merging said transform file into a transform program for transforming the communicated code of said first information processing system to the format of the code of said second information processing system.
Claim 3
Dependent Claim
43 words
The interactive control system of claim 1 wherein said means for selectively replacing certain ones of said default characters and control instructions includes means for replacing a single byte character of the first format with a single byte character of the second format.
Claim 4
Dependent Claim
43 words
The interactive control system of claim 1 wherein said means for selectively replacing certain ones of said default characters and control instructions includes means for replacing a single byte character of the first format with a multi-byte character sequence of the second format.
Claim 5
Dependent Claim
41 words
The interactive control system of claim 1 wherein said means for selectively replacing certain ones of said default characters and control instructions includes means for replacing multi-byte character sequences of the first format with multi-byte character sequences of the second format.
Claim 6
Dependent Claim
203 words
In a data communication system including a first information processing system which operates on internal code of a first format and a second information processing system which operates on internal code of a second format different from said first format, a method for interactively transforming the communicated code of said first information processing system to the format of the code of said second information processing system comprising the steps of: (a) displaying to an operator of the second information processing system a menu of code format transform tasks available for operator selection; (b) selecting one of said code format transform tasks in response to an operator input to the data communication system; (c) displaying a transform file of characters and control instructions of said first information processing system together with corresponding default characters and control instructions in the format of the second information processing system; (d) selectively replacing certain ones of said default characters and control instructions in said transform file with characters and control instructions selected by the operator; and (e) merging said transform file into a transform program for transforming the communicated code of said first information processing system to the format of the code of said second information processing system.
Claim 7
Dependent Claim
203 words
In a data communication system including a first information processing system which operates on internal code of a first format and a second information processing system which operates on internal code of a second format different from said first format, a method for interactively transforming the communicated code of said first information processing system to the format of the code of said second information processing system comprising the steps of: (a) displaying to an operator of the second information processing system a menu of code format transform tasks available for operator selection; (b) selecting one of said code format transform tasks in response to an operator input to the data communication system; (c) displaying a transform file of characters and control instructions of said first information processing system together with corresponding default characters and control instructions in the format of the second information processing system; (d) selectively replacing certain ones of said default characters and control instructions in said transform file with characters and control instructions selected by the operator; and (e) merging said transform file into a transform program for transforming the communicated code of said first information processing system to the format of the code of said second information processing system.
Claim 8
Dependent Claim
27 words
The method of claim 5 wherein step (d) further includes selectively replacing single byte characters of the first format with single byte characters of the second format.
Claim 9
Dependent Claim
27 words
The method of claim 5 wherein step (d) further includes selectively replacing single byte characters of said first format with multi-byte character sequences of the second format.
Claim 10
Dependent Claim
