I am using CW 8.1 for 56F803 using USBTAP. I am new to CW. In the expressions window, I can view the variable defined in C. However, when I put the variables defined in asm to expressions window, it says "undefined identifier in expression". These variables are defined in asm file and "extern" keyword is used in C file. The program also gives correct result. Is there a way to display the global variables that are defined in assemble code? Thanks.
