Input Statement Help

christ0fr — Thu, 22 Nov 2018 16:32:47 GMT

Hi,

I'm trying to run some very simple code to read a file (attached). I expect 7 variables Q1 through 7 each with one one-digit number; however, the code below gives me a 7 digit number in Q1, the age in Q2, the IQ in Q3. I tried putting spaces between the Q1-Q7 data in the dat file, but then I get every variable with only one digit (i.e., AGE will be one digit with the second digit being placed in IQ). I'm a new SAS user working my way through exercises and this was one that I couldn't make work (even using a datalines statement instead of infile).

Thanks

data D1;
	infile 'C:/Users/myname/Desktop/volunteer.txt';
	input	#1	@1	Q1-Q7	1.
			@9	AGE	2.
			@12	IQ	3.
			@16	NUMBER	2.
			@19	SEX    $1. ;
RUN;

Hi @christ0fr and welcome to the SAS Support Communities!

You just forgot the parentheses:

input @1 (Q1-Q7) (1.)

Put brackets around the Q and format. I don't think you need the #1 either.

data D1;
	input   @1	(Q1-Q7)	(1.)
			@9	AGE	2.
			@12	IQ	3.
			@16	NUMBER	2.
			@19	SEX    $1. ;
