Abstract

PURPOSE:To use the storage contents of a memory of a data processor effectively by regarding the storage starting position of a user program area and the storage starting position of a data area as a starting address and ending address of the memory. CONSTITUTION:A user program that a user is to use, when inputted via a tape reader RTR, is supplied to a CPU2 via an input-output part 1 and the program is stored by using addresses (0)-(i) of a RAM4. When data on a document is inputted from a keyboard, the CPU2 reads a data processing program, which corresponds to the user program read from the RAM4, from ROM3 to process the data and then stores the result in the ending address (n) of the RAM4. Data processed next are stored in addresses n-1, n-2... successively and the data are collected. The address (i) as the boundary between a user program area and data area is freely variable.
