<p>In a system for writing ROM cassette for a programmable machine controller, to write a PMC program prepared on a RAM onto the ROM cassette, provision is made of: a reading means which successively reads the data stored in said RAM starting from a final address; a discrimination means which discriminates whether the data read by said reading means is a specific code or not; an address detecting means which detects the address of said RAM which stores the data that was first discriminated by said discrimination means not to be said specific code; and a writing means which successively writes the data stored in said RAM starting from the head address; wherein said writing means is so constituted as to successively write the data onto said ROM cassette from the head address of said RAM through up to the address detected by said address detecting means. The address detected by the address detecting means is an address of the RAM which stores a final portion of the PMC program. Therefore, the writing means writes onto the RAM cassette the data of only a portion where the PMC program is stored.</p> |
