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

[nbauer1201]

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

Thanks again,

What do you think the $ does in this line?

input time event $treatment;

[nbauer1201]

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

[dkb · Accepted solution]

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.
