Create a program that allows a user to select a number base

Q For this assignment you will create a program that allows a user to select a number base (in the range of 2 to 16, inclusive), enter digits for the number base, validate each digit as it is entered, and display the resulting value in base 2, 8, 10 and 16.

 

Requirements

Create a program that:

 Has six user-defined procedures (UDPs):

 o IsLegal – this UDP shall:

 Accept an ASCII value in one register.

 Accept a number base value in another register.

 Determines whether the ASCII value is valid for the base.

 Use the AsciiToDigit procedure

 Return 1 if the value is valid.

 Return 0 if the value is not valid.

 o AsciiToDigit – this UDP shall:

 Accept an ASCII character value in a register.

 Returns the numeric value related to the ASCII character value. For example, if

 ‘A’ (41h) or ‘a’ (61h) is passed in, then this procedure would return 10d.

 Return -1 if the ASCII character is not valid.

 o DigitToAscii – this UDP shall:

 Accept a numeric value in a register.

 Returns the ASCII character value related to the numeric value. For example, if

 15d is passed in, then this procedure would return ‘F’ or ‘f’ (you must choose one

 case for letters).

 Return -1 if the numeric value is not valid.

 o WriteInteger – this UDP shall:

 Accept a number in the EAX register.

 Accept a number base value in the BL register.

 Display the number in its base. For example, if 5 and 2 were passed in, this UDP

 would display 101.

 Use the DigitToAscii procedure.

 Not display leading zeroes.

 o ReadInteger – this UDP shall:

 Accept a number base in the BL register.

 Read characters from the keyboard one character at a time until the user presses

 the Enter key.

  The valid characters are ‘0’ – ‘9’, ‘a’ – ‘f’ and ‘A’ – ‘F’.

 Validate each character, as it is entered, to ensure it is a valid character for the

 number base. For example, entry of ‘G’ for base 7 is invalid, but ‘6’ would be

 valid.

   If a character is valid, display it on the screen.

   If a character is invalid, then do not display it.

  Maintain a running final value as each character is entered.

   For example, if a user chose base 7 and entered the digits 2, 6, 7, A and1:

  o The 7 and A would be ignored leaving 2617.

  o Your running value would consist of calculating the decimal

  value of (2 * 72) + (6 * 71) + (1 * 70) = 141.

 Not use an array.

 Return the result in the EAX register.

 Return 0 if no valid characters were entered.

 o DisplayIntegers – this UDP shall:

 Accept a number in the EAX register.

 Use the WriteInteger procedure to display number in its Base 2, Base 8, Base 10

 and Base 16 equivalents.

 Performs the following tasks in the main procedure:

 o Prompts the user for a number base value.

 o Uses the ReadInteger procedure to get the base value from the user.

 If the ReadInteger procedure call results in 0 then you will exit the program.

 If the ReadInteger procedure call results in a value outside of the range of 2-16,

 then display an error message and prompt the user again.

 o Prompts the user for a number.

 o Uses the ReadInteger procedure to get the number from the user.

 o Uses the WriteInteger procedure to display the user-entered number in its Base 2, Base 8,

 Base 10 and Base 16 equivalents.

 o Allows the user to enter another base/number combination.

 Is formatted and commented as required by the CS370 Coding and Documentation Standards.

 Does not use the .IF, .REPEAT, or .WHILE directives of MASM.

 

Allowed Irvine Procedure Calls:

 Crlf

 ReadChar

 WriteChar

 WriteString
