Modifying A SAS Data set after it was created using PROC IMPORT - excel

Question

I have a dataset like this
Obs MinNo EurNo MinLav EurLav
1 103 15.9 92 21.9
2 68 18.5 126 18.5
3 79 15.9 114 22.3
My goal is to create a data set like this from the dataset above:
Obs Min Eur Lav
1 103 15.9 No
2 92 21.9 Yes
3 68 18.5 No
4 126 18.5 Yes
5 79 15.9 No
6 114 22.3 Yes
Basically I'm taking the 4 columns and appending them into 2 columns + a Categorical indicating which set of 2 columns they came from
Here's what I have so far
PROC IMPORT DATAFILE='f:\data\order_effect.xls' DBMS=XLS OUT=orderEffect;
RUN;
DATA temp;
INFILE orderEffect;
INPUT minutes euros ##;
IF MOD(_N_,2)^=0 THEN lav='Yes';
ELSE lav='No';
RUN;
My question though is how I can I import an Excel sheet but then modify the SAS dataset it creates so I can shove the second two columns below the first two and add a third column based on which columns in came from?
I know how to do this by splitting the dataset into two datasets then appending one onto the other but with the mode function above it would be a lot faster.

Answer 1

You were very close, but misunderstanding what PROC IMPORT does.
When PROC EXPORT completes, it will have created a SAS data set named orderEffect containing SAS variables from the columns in your worksheet. You just need to do a little data step program to give the result you want. Try this:
data want;
/* Define the SAS variables you want to keep */
format Min 8. Eur 8.1;
length Lav $3;
keep Min Eur Lav;
set orderEffect;
Min = MinNo;
Eur = EurNo;
Lav = 'No';
output;
Min = MinLav;
Eur = EurLav;
Lav = 'Yes';
output;
run;
This assumes that the PROC IMPORT step created a data set with those names. Run that step first to be sure and revise the program if necessary.
