For this application, press F7 or select Project→Make.

Step 8: If you entered the text exactly as in Table 1, you should get an error when you compile at the line 
LCALL   Hex2Asc2
To point to the source of error, double click on the error line in the message window. Retype the line t LCALL Hex2Asc and recompile.
