PROBLEM TO BE SOLVED: To precisely recognize the idle capacity of a memory by outputting all file ID under a current-only file. SOLUTION: When a 'BROWSE' command is given from a reader/writer device, CPU executes pre-execution check (S401). Then, CPU retrieves an operation file and transmits data (S405). In such a case, all the files which have current DF in master DF and which are entered from a file entry table are retrieved (S406), and whether the pertinent files exist or not is judged. When the pertinent file exists, (S407), the file is set in the transmission area of RAM. Then, CPU judges whether the transmission work area in RAM becomes full or not (S409), When it becomes full, a transmission module is called and a retrieval result till that time is transmitted (S411). |
