To transfer to the monitor, you need to execute a BRK instruction, which transfers control to the software interrupt vector which in turn transfers control to the monitor in the ROM. SYS 1024 transfers control to location 1024 which is always zero. You can actually SYS any address containing a zero byte and be transferred to the monitor. > Now, Let's suppose you enter a program using the Monitor (after > getting the hex code from assembling it in another computer), then, how to sa ve > it in a disk? An easy way might be to write a simple basic program that did PEEKs at the range of memory used by your code and write that one byte at a time to a .PRG file opened as a sequential byte file. You write on the "loader" header that tells the basic loader where your assembly code should be loaded. We had a discussion about this very subject on this list just a few weeks ago -- I was asking the same questions. -- "The Direct3D Graphics Pipeline"-- code samples, sample chapter, FAQ: <http://www.xmission.com/~legalize/book/> Pilgrimage: Utah's annual demoparty <http://pilgrimage.scene.org> Message was sent through the cbm-hackers mailing list
