	array the compiler issues an internal compiler error message. When the
	option -qdebug=except:tracebk is specified the compiler issues a 
	traceback from CS_PRF.
IX09662 If a function is being passed to another procedure or function and both
	routines are undefined the compiler issues an internal compiler error
	message.  When the option -qdebug=except:tracebk is specified the
	compiler issues a traceback from ADVANCE_CONTEXT.
IX09661 Passing a pointer to a record field to a procedure or function causes 
	the length of the entire record, instead of the length of the record
	field to be passed as the parameter descriptor.
IX09660 Passing expressions as parameters to a function may cause unpredicatable
	execution or incorrect results when the -O option is not specified.
IX09659 Options that should appear before all executable code are being accepted
	anywhere in the source file.
IX09653 Incorrect results when compiled with -O option.
IX09650 The compiler issues an internal compiler error message when the -O
        option is specified.  When the option -qdebug=except:tracebk is also
        specified the compiler issues a traceback from EQUIVALENT_DEFS.

        input to them is a parameter or a record field of type subrange.
