Sas loop through a list
Webb4 mars 2016 · To make macro loop driven by data we can use two index macro variables: the first one (primary index) iterates from 1 to n incrementing by 1 effectively going through the observations of a driver table, the other macro variable (secondary index) gets its values from the driver variable and is being a true data-driven index for our macro loop.

WebbWe are facing two options: list these variables one by one in the VAR statement or write a few lines of code to dynamically generate the list of these variables. For a repetition of so many items, the following code is a better solution: %MACRO DO_LIST; %DO I = 1 %TO 50; COL&I._LINE1 %END; %MEND DO_LIST; Invoking macro DO_LIST in the VAR statement WebbSyntax: do i = n to m; n and m are counter variables. 2.

WebbSAS DO LOOPS So we have now defined our arrays, but now we have to use them to manipulate the data. We use a DO loop to perform the data manipulations on the arrays. Within a DATA step, a DO loop is used to specify a set of SAS statements or operations that are to be performed as a unit during an iteration of the loop.
WebbComposite Iterator Key, Nested Loop The single loop iteration of composite keys is inefficient and inconvenient. Using nested loops to separate each member of the key into iteration levels should be a more convenient approach.
