NEED HELP WITH LC3 LANGUAGE PROGRAM IN PART 2

PART 2: Add code that parses the non-numeric part of the input string, and calls the appropriate parser for decimal or hexadecimal. You do not need to parse the number part yet. Your code should be placed in the file where it says Insert your code for part 2 here!. Also, you need to copy the code you wrote for part 1 to where it says Insert your code from part 1 here!. Copy only the code you wrote in part 1, do not copy the code that was already there. Your code must start with a label named ProcessInputCore. On entry to your code, R2 will contain the address of a null terminated string containing the number to parse On exit from your code, R1 must contain zero if the number is positive and -1 if it is negative R2 must contain the memory location of the first digit of the number (ie. after the minus sign and x or #). The code should branch to ParseHex if it determines that the number is hexadecimal, and ParseDecimal if it determines that it is decimal. Style requirements: Beyond making sure that your programs function correctly, it is important that they are documented thoroughly and correctly. Good programming style makes your programs easy to read and to understand, both by you and by anyone else who needs to understand or to change your code in some way. Furthermore, programs written following appropriate style guidelines are easier to write and debug than programs written in a haphazard, disorganized style. While the assembler does not care about the programming style you use, the goal of good style is to make the program easy for people to read. 1. Your assembly language programs should have the following comment block at the top of the file. ; ; Name(s): ; Course number: ; Lab number/problem number: ; Due date: ; 2. All symbolic labels must be meaningful. It is helpful to use both lower and upper case to help make the names easy to read. For example, use SaveR1 as a label instead of something more cryptic, such as SR1. Other good examples include names such as, EndProgram, ReadKeyboard, PrintResult, ShiftLeft, and so on. 3. Add a comment after each instruction to describe what it is doing with regard to the overall program. 4. Use white space (i.e., spaces, tabs, carriage returns) generously to emphasize the structure of your program and to make it easy to read. Make sure you indent and align statements and comments appropriately. 5. No lines should be more than 80 characters long.
