Discussion

The evalprogramsymbol function searches each program loaded in the current context for the specified symbol. If the symbol is found, its value is returned. Otherwise, an error message is displayed.

The value returned for a data symbol (variable) is its current state in the target. The value of a code symbol is its address.
