To solve the problem of converting a 4-digit ASCII input string into an equivalent hexadecimal number in 8086 assembly language, we can break the task down into the following steps: ### Algorithm: 1. Input the 4 ASCII Digits: - Read 4 ASCII digits (e.g., '4', '5', '3', '2') one by one. Each digit represents a number in the range 0-9 or A-F (for hexadecimal). 2. Convert ASCII to Decimal: - The ASCII code for the digits '0'-'9' is in the range 0x30 to 0x39. To convert the ASCII digit to its actual decimal value, subtract 0x30 (48 in decimal). 3. Calculate the Hexadecimal Equivalent: - Start with an initial value of 0. - Multiply the accumulated value by 10 (shift the place value) and add the decimal value of each ASCII character. - After processing all 4 digits, the result will be the decimal equivalent of the number. 4. Convert Decimal to ___ ______ _________ _____ _________ ___ ____ ____ _______.
