Annoying with F10 While debugging

I'm debugging an RPG IV program. The program hits a chain. The next step goes to the F spec for the file being accessed. I press F10 to step, but the cursor stays on the F spec until finally moving back into the program. Why does this happen, and is there some way to prevent it?

Answer:
The debugger steps once for each input (or output) specification in the record format. Put OPTION(*NODEBUGIO) in an H spec.

I recommend you also include the *SRCSTMT option, so that the compiler uses the sequence numbers from your source member:

OPTION(*SRCSTMT : *NODEBUGIO)
