I FA The Negative and Zero flags of the Status register are conditioned by the load operation. Store instructions The reverse process of placing a register's contents into a memory location, is known as storing. There are three store instructions: 38 STA STX STY STZ Store accumulator Store X register Store Y register Store a zero (65C02 only) The register value is unaltered and no flags are conditioned. Example: LDA#O STA $1500 Accumulator ~00__~------------••~1 $1500 00 Transfer instructions Instructions are provided to allow the contents of one register to be copied into another- this is known as transferring.
4 shows the result of a typical run of the program. Once the machine code has been entered, it can be tested by using the CALL command followed by the address (in decimal) of the first byte of the machine code program. In this case, the program can be run by typing 'CALL 768'. APPLE HEX LOADER ASSEMBLY ADDRESS: 768 768: 769: 770: 771: 773: 774: SA9 SCI S20 SED S60 SSTOP Fig. 4 A sample rnn of the Apple Hex Loader program. CALLING MACHINE CODE To execute a machine code program, the Applesoft BASIC statement 'CALL' is used.
Line 90 Line 110 Gets the high nibble of the hex byte. Line 120 Saves its value in HIGH. Line 130 Prints the high nibble. Line 150 Gets the low nibble of the hex byte. Line 160 Saves its value in LOW. Line 170 Prints the low nibble. Calculates the value of the byte. Line 180 Line 200 POKEs the value of the byte into memory. Line 210 Increments the memory counter. Repeats the entire process. Line 220 Line 2000 Wait for a key to be pressed. Line 2010 If it's an S print the word STOP and end the program.
