ERROR: Variable event in list does not match type prescribed for this list.

I'm receiving an error pertaining to variables that I thought I had covered. I am a novice at writing SAS and would appreciate any help I can get. Here is the code that I wrote and the associated error message. Thanks in advance for your help!!!

data rats;

length treatment $ 8;

input time event $treatment;

datalines;

18 1 Group0 23 1 Group0

25 1 Group0 26 1 Group0

29 0 Group0 30 1 Group0

30 1 Group0 31 1 Group0

31 0 Group0 32 0 Group0

13 1 Group1 13 1 Group1

15 1 Group1 17 1 Group1

17 0 Group1 18 1 Group1

18 1 Group1 21 1 Group1

23 1 Group1 23 0 Group1

24 1 Group1 25 1 Group1

25 1 Group1

;

ods graphics on;

proc lifetest data=rats atrisk conftype=asinsqrt

plots=(survival(cb=ep atrisk) loglogs logsurv);

time time*event(0);

strata treatment;

run;

ods graphics off;

42	ods graphics on;
43	proc lifetest data=rats atrisk conftype=asinsqrt
44		plots=(survival(cb=ep atrisk) loglogs logsurv);
45		time time*event(0);

ERROR: Variable event in list does not match type prescribed for this list.

46		strata treatment;
47	run;

Thanks again,

Nathan

What do you think the $ does in this line?

input time event $treatment;

Doesn't the $ tell sas that it is a character value?

On an list-style input statement, it says that the preceding variable is a character variable.

But since SAS already knows that treatment is a character variable - you've told it in the previous line...

length treatment $ 8;

... you don't need to use $ at all in your input statement. This will work fine:

data rats;

length treatment $ 8;

input time event treatment;

datalines;

18 1 Group0

...

I can't thank you enough! That absolutely fixed it!!!! It ran with no problems. I was clearly being redundant.
