If i pick you for this work, email me and i will send you the sample program.
Modify a program that converts lower case characters found in a sequence of adjacent memory locations to their corresponding upper case value. The modification of this program is to alter upper case characters to lower case (just the opposite action of the original program).
In this program, note how the value of characters in the sequence, have an apostrophe in the front and at the end of the sequence. The size of the data is defined as a byte (DB). The conversion between upper and lower case is identified as the difference of 32, one bit either on or off in the byte. Also note that only alphabetic characters can be converted, special symbols such as punctuation characters and digits are ignored (skipped).
Save the working program as [login to view URL] in your CETU331 directory. Now that you have this working code, make a copy of it and save it as HW02SLNB.ASM.
In the copy of your working solution (HW02SLNB) remove the looping code that checks and possibly alters the value of the characters and place it in a subroutine. The main program will access the subroutine using a call statement. This new subroutine (or function) will take the count of the number of values to be manipulated in the **CX** register, the OFFSET to the first value of source data in memory is in the **SI** register and the OFFSET to the destination of the data in the **DI** register.
As a subroutine, this code should be documented as to its purpose, the registers that it affects and where the results should be located upon completion of the code.
