ERROR: "LINE and COLUMN cannot be determined."

[somebody]

I receive t he following error message when I ran the below code. Can anyone please figure out why? 

What my code is trying to do is to create a number of trading dates after each date in the temp_sample dataset

data temp_sample(drop=d d0 trdate t); 
	array trdates {200000} _temporary_; 
		if _n_=1 then do d=1 by 1 until (end_of_trcalendar); 
			set tradingdays (keep=trdate) end=end_of_trcalendar; 
			trdates{d}=trdate; 
		end; 
	set temp_sample ; 
	format date_t0 YYMMDD10.;

	by &stockid. date; 
	if first.date; 
	date_t0=date; 
	d0=whichn(date_t0,of trdates{*}); 
	do T=1 to &holding_period.; 
		date=trdates{d0+t}; 
		output; 
	end; 
	rename date_t0=form_date;
run;

And the error messages are:

180: LINE and COLUMN cannot be determined.
NOTE: NOSPOOL is on. Rerunning with OPTION SPOOL might allow recovery of the LINE and COLUMN where
      the error has occurred.
ERROR 180-322: Statement is not valid or it is used out of proper order.

You usually only see that for macro code, but your posted code has no macro definition or macro call.

Are you defining and using a macro?

[Tom]

Make sure the values of the two undefined macro variables in your code are appropriate.

Not sure what you are trying to do, but perhaps you have indexed outside of your array? There are some simple things with loop boundaries you can do to make the logic better at preventing errors. 

if _n_=1 then do d=1 to dim(trdates) until (end_of_trcalendar); 
...
do T=1 to min(&holding_period.,dim(trdates)-d0+1);
