EMU8086 REGISTER KEY CODE
Generally, macro is a relatively small code segment. When the compiler runs your code, it first finds the declaration.Įmu8086.inc File, then use the macros in the code to actually
EMU8086 REGISTER KEY PLUS
The method of using the above macro is: Write the macro name plus parameters in the bit value you need. Somety with the print function,ĭifferentiated automatic enter after output PRINTN string- Output strings, one parameter.PRINT string- Output string, one parameter.GOTOXY col, row - Set the current cursor position, there are two parameters.PUTC char- Output an ASCII character to the cursor current bit value, only one.Need to use emu8086.inc The function, you should open in your program Usually you can't fully understand emu8086.inc (lie in Inc folder)īut this doesn't matter, you only know what it can do is enough. I will automatically find you in the folder where your source program is located.įile, if not found, it will search Inc folder. INCLUDE Then the file you want to reference later.

Each time this procedure is called, it reads a number from the keyboard until any key other than 0 through 9 is typed. If a larger result is required, the procedure must be reworked for 32-bit arithmetic. Here the binary number returns in the AX register as a 16-bit result. Repeat steps 2 and 3 until the character typed is not an ASCII coded number of 30H-39H.Įxample 1 illustrates a procedure that implements the ASCII-to-binary conversion algorithm. Multiply the binary result by 10 and add the new BCD digit. Subtract 30H from the character typed on the keyboard to convert it to BCD. The algorithm used to convert ASCII to binary is: 1. After subtracting 30H, the prior result is first multiplied by 10, the number is added to the result. If more than one key is typed, conversion from ASCII to binary still requires that 30H be subtracted, but there is one additional step. If a single key is typed the conversion is accomplished by subtracting a 30H from the number.
