I need help coding this in assembly. We are told to use the ReadChar function to read the character value in and then convert it to ASCII. This includes all values 0 through F.

The objective of this exercise is to write the procedure DigitValue2ASCII that converts a value v of a hexadecimal digit d into the ASCII code of the digit d. The procedure DigitValue2ASCII uses the register AL as parameter. We assume that AL contains a value between 0 and 0Fh=(15)₁₀. Therefore, AL will contain the value of a hexadecimal digit 0 to F. You do not have to test AL for the range. The procedure DigitValue2ASCII must return in the register DL the ASCII code of the digit d.

Examples:

1) If AL contains the value 4, procedure DigitValue2ASCII returns in DL the ASCII code of 4, i.e. DL = 34h.

2) If AL contains the value 0Ch=(12)₁₀, your procedure return in DL the ASCII code of C, i.e. DL = 43h.
