How to save OUT results in a name variable in SAS

[mapk]

I tried to convert wide format data to long format but it only gives me the result in output format. I would like to save the output of this in a variable name (sirstvt_long) and be able to print it as print(sirstvt_long). Also, I would like to drop Subject columns and sort this table by instrument column (starting with I1, I2,..I5). How do I do this in SAS?  Sorry I am new to SAS and your help would be appreciated.

data sirstvt;
  infile 'https://www.itl.nist.gov/div898/strd/anova/SiRstvt.dat' url firstobs=61 truncover;
  input I1-I5 ;
run;

data sirstvt;
set sirstvt;
Subject+1; 
run;

proc transpose data=sirstvt 
   OUT=sirstvt_long(rename=(Col1=Resistance)) name=Instrument;                    
   by Subject;                   /** for each subject **/
   var I1 I2 I3 I4 I5; /** make a row for these variables **/
run;

print(sirstvt_long);

Result I want should be in this format:

Instrument Resistance
1 196.3052
1 196.1240
1 196.1890
1 196.2569
1 196.3403
2 196.3042
2 196.3825
2 196.1669
2 196.3257
2 196.0422

Without knowing the content of you in file I can't actually run the first part of the code to verify it. But assuming that that one works, instead of your last line you could replace it with the following code:

*Sort the table by your I(n) variables and drop the column subject; 

proc sort 	data=sirstvt_long 
		out=sirstvt_long_2 (drop=subject);
	by I1 I2 I3 I4 I5;
run;

*Print the table, but don't show row number in the output. Also use labels if there are any.;
proc print data=sirstvt_long_2 noobs label;
run;

This will print the table on screen. Do you want it written to a space separated text file?

Not sure why I am still getting this error:

I read your code a bit to fast. Yes, I1-I5 does not exist anymore, they have been transposed to the variable Instrument.

Instead of  

	by I1 I2 I3 I4 I5;

I had to use 

by Instrument

It worked now. Thanks a lot.

For the public record, the data extracted from the URL you're referencing is tantamount to:

data sirstvt ;                               
  input i1-i5 ;                              
  cards ;                                    
196.3052 196.3042 196.1303 196.2795 196.2119 
196.124  196.3825 196.2005 196.1748 196.1051 
196.189  196.1669 196.2889 196.1494 196.185  
196.2569 196.3257 196.0343 196.1485 196.0052 
196.3403 196.0422 196.1811 195.9885 196.209  
run ;                                        

To get what you want as shown in your output sample, there's no need to sort:

data sirstvt ;                                                                               
  infile 'https://www.itl.nist.gov/div898/strd/anova/SiRstvt.dat' url firstobs=61 truncover ;
  input i1-i5 ;                                                                              
  put i1-i5 ;                                                                                
run ;                                                                                        
                                                                                             
proc transpose out = _sirstvt ;

  Instrument = _n_ ;

  end ;                                                                                      
  format Resistance 8.4 ;
