Abstract

In a program specification data transfer method for program development support system according to the present invention, if a program specification data program is updated in the editing by the specification data edit unit at the terminal, then the update flag of the applicable specification data program is set to indicate the existence of update by the update flag set unit. The updated data extract unit checks the update flag to extract the updated program specification data alone and thus extracted updated program specification data is transferred to the work file at the host computer. The specification data merge unit merges the updated program specification data stored in the work file with the program specification data in the program specification data file at the host computer and stores the merged result to the program specification data file.

Claims

1. A program specification data transfer system for program development support system comprising a host computer and a terminal,

the host computer including:

a host program specification data file to store the program specification data for program generation,

a work file to temporarily store an updated data transferred from the terminal,

host transfer means for transferring the program specification data in said host program specification data file to the terminal, and

specification data merge means for merging the updated data stored in said work file with the program specification data in said host program specification data file and storing a merged program specification data in said host program specification data file, and

the terminal including;

a terminal program specification data file to store the program specification data transferred from said host computer,

edit means for editing the program specification data in said terminal program specification data file,

updated data extract means for extracting only the updated data from said program specification data after editing, and

terminal transfer means for transferring only the updated data extracted by said updated data extract means to said work file at said host computer,

said program specification data has an update flag for judging whether the data is updated or not, and said terminal has an update flag set means for setting an update information at the update flag in said program specification data updated during editing by said edit means,

said updated data extract means judges whether said program specification data after being edited was updated or not by checking the update flag in said program specification data and extracts only the updated data.

2. A program specification data transfer system for program development support system of claim 1 wherein said host computer has an update flag cancel means for setting the indication showing the lack of updating in the update flag in the program specification data held in said work file when said specification data merge means performs merging.

3. A program specification data transfer system for program development support system comprising a host computer and a terminal,

the host computer including:

a host program specification data file to store the program specification data for program generation,

a work file to temporarily store an updated data transferred from the terminal,

host transfer means for transferring the program specification data in said host proqram specification data file to said terminal, and

specification data merge means for merging the updated data stored in said work file with the program specification data in said host program specification data in said program specification data file and storing a merged program specification data in said host program specification data file, and

the terminal including;

a terminal program specification data file to store the program specification data transferred from said host computer,

edit means for editing the program specification data in said terminal program specification data file,

updated data extract means for extracting only the updated data from said program specification data after editing, and

terminal transfer means for transferring only the updated data extracted by said updated data extract means to said work file at said host computer,

wherein said program specification data further has an update flag for judging whether the data is updated or not,

said terminal has an update flag set means for setting an update information at the update flag in said program specification data updated during editing by said edit means, and

said host computer has an update flag cancel means for setting the indication showing the lack of updating at the update flag in the program specification data held in said work file when said specification data merge means performs merging, and

said update data extract means judges whether said program specification data after being edited was updated or not by checking the update flag in said program specification data and only extracts the updated data from said program specification data.

4. A program specification data transfer system for program development support system comprising a host computer and a terminal,

the host computer including:

a host program specification data file to store the program specification data for program generation,

host transfer means for transferring the program specification data in said host program specification data file to said terminal, and

specification data merge means for merging the updated program transferred from said terminal with the program specification data in said host program specification data in said program specification data file and storing merged program specification data in said host program specification data file, and

the terminal including;

a terminal program specification data file to store the program specification data transferred from said host computer,

edit means for editing the program specification data in said terminal program specification data file,

updated data extract means for extracting only the updated data from said program specification data after editing, and

terminal transfer means for transferring only the updated data extracted by said updated data extract means to said host computer,

wherein said program specification data further has an update flag for judging whether the data is updated or not,

said terminal has an update flag set means for setting an update information at the update flag in said program specification data updated during editing by said edit means, and

said host computer has an update flag cancel means for setting the indication showing the lack of updating at the update flag in the program specification data merged by said specification data merge means, and

said updated data extract means judges whether said program specification data after being edited was updated or not by checking the update flag in said program specification data and extracts only the updated data from said program specification data.
