Hello

I have a code that do not understand and was wondering if someone can help me with. I am attaching the data before and after as an EXCEL file.

Thank you

Code:

data new;

set old;

do combinations=1 to 32;

Hi ,

"do combinations=1 to 32;" added a variable "combinarions" to dataset old and increased the obsevations to 32*(number of obs. in dataset old).

example:

data old;

input
a b;

cards;

1 2

2 1

;

data
new;

set
old;

do combinations=1 to 32;

output;

end;

run;

proc sort data=new;

by combinations;

run;
