Used by the routine at MAIN_EXEC.
The parsing routine of the BASIC interpreter is entered here when syntax is being checked, and at LINE_RUN when a BASIC program of one or more statements is to be executed.
Each statement is considered in turn and the system variable CH-ADD is used to point to each code of the statement as it occurs in the program area or the editing area.
