Data <new name>; 

Retain <variables>; can be used to set the order of variables in the table (must come before the set statement)

Set <libref.file>; libref not required if the file is in the working library

Length <variable><$> W or <variable> w.d; where W=number of print places for character variable or for numerical W=bites and .d = decimal places

Assign new variables; type new variable name and then define



Where; create a data subset by limiting the table to a particular level of a variable

Drop <variables>; if the drop statement is used within set statement then variables are not read into the PDV (drop= ) and are thus not available for processing

Keep <variables>; limits the variables that are saved to the new dataset

If condition;



Multiple data sets an be created in one data step, which is best done with a select function:

Select (<variable>);

When ('level1') output <data1>;

When ('level2') output <data2>;

Otherwise; optional to otherwise output other



To avoid errors due to capitalisation, use the upcase or lowcase function, e.g., select (lowcase(<variable>))


To collapse levels of a variable, e.g, to collapse value 3 into 2

<variable2> = <variable1>;

if variable1=3 then variable2=2;


Converting character to numerical variables:

numvar = INPUT(charvar, best32.);


<variable> = <variable> + 0
