I don't believe there is a way to step thru an include file. #'s define things to happen at compile time, prior to runtime. So anything defined in the #include will have already happened.

>When I want to step through a program I normally open the program set a break point then run the program, form or whatever. I can then step through the code. But a person sent me a program with a #include statement and when I run the program in interactive mode the defined constants are not available. What am I doing wrong? And how would you step through such a program?
