How to adjust the code to test the automatic variable _ERROR_ ?

Hi all,

I just learnt from @Reeza a good tool regarding put_all_; to see what seemingly works behind the scene.

So, in the compilation step, after the input buffer is the PDV step. In this step, SAS will create two automatic variables named _N_ and _ERROR_

I am wondering how to adjust the code below to see _error_ different from 0.

data storm_complete;
	set pg2.storm_summary_small;
	length Ocean $ 8;
	where Name is not missing;
	Basin=upcase(Basin);
	StormLength=EndDate-StartDate;

	if substr(Basin,2,1)="I" then
		Ocean="Indian";
	else if substr(Basin,2,1)="A" then
		Ocean="Atlantic";
	else Ocean="Pacific";
	drop EndDate;
	put _all_;
run;

The log is

Name=AGATHA Basin=EP MaxWind=115 StartDate=09JUN1980 EndDate=15JUN1980 StormLength=6
Ocean=Pacifi _ERROR_=0 _N_=1
Name=ALBINE Basin=SI MaxWind=. StartDate=27NOV1979 EndDate=06DEC1979 StormLength=9 Ocean=Indian
_ERROR_=0 _N_=2
Name=ALEX Basin=WP MaxWind=40 StartDate=09OCT1980 EndDate=14OCT1980 StormLength=5 Ocean=Pacifi
_ERROR_=0 _N_=3

I tried to delete some semicolon but the code just stop working rather than announce the _error_ different from 0.

Thank you!

Try dividing by zero, log of a negative number, subscript out of bounds, or any other error condition.
