PURPOSE:To omit the manual operation for control of program data and to reduce the read/write time loss by providing an area to store the program names and an area to store the programs. CONSTITUTION:The program data are stored to a RAM8 serving as a main memory and then written to a flexible disk memory FD10 serving as an auxiliary memory and a fixed magnetic disk device HD12. In this case, the program name is written to the FD10 which contains the areas where the program names and the programs are written. When a program is written, the program data is called out of the RAM8. Then the directory of the FD12 is read out of the FD10 to check the presence/absence of the same program name. The program data is written to a data block of the FD10 corresponding to the relevant block table as long as an idle area equivalent to the number of blocks of the program to be recorded. |
