Rather than explain the project, I have listed the Link below.<br /><br /><a href="http://www.eecs.utoledo.edu/~jguernse/_pdf/project2.pdf" target="_blank">http://www.eecs.utoledo.edu/~jguernse/_pdf/project2.pdf</a><br /><br />I have started both the box program and the hex convert program but am having trouble completing the hex code. The box code works, however, I am going to have to link the hex convert file in the middle of the box program to meet the project requirements. If anyone could help me complete the hex convert program, (and possibly link it in the middle of the box program) I would really appreciate it. <br /><br />My codes are listed below.<br /><br />First listed is the Hex convert code:<br /><br /><!--c1--><div class='codetop'>CODE</div><div class='codemain'><!--ec1--><br />; Filename: puthex<br /><br />INCLUDE PCMAC.INC<br />.MODEL SMALL<br />.586<br />.STACK 100h<br /><br />        CR     EQU     10d<br />        LF     EQU     13d<br />.DATA<br />        ERR    DB    40h<br />        msg1    DB    'Enter 10 digits.
