Loop through datasets in SAS

This code was found here. It lets you loop through datasets in a SAS-library and tries to print the first 10 observations from each dataset in the SAS-library.

 

Call Execute lets you run PROC-statements in a datastep. It will simply execute the proc-statement after finishing the datastep. It is also possible to use ‘if‘, ‘then‘ and ‘else‘ in the datastep to execute certain parts of the code based on some value.
This is of course also possible through macro-code.

Loop a delimited macrovariabel in SAS

This shows how to loop a delimited macrovariabel.

%let Delimitor = ¤;
%let Logins = Login1¤Login2;

%let NumberOfLogins = %sysfunc(countw(&Logins., &Delimitor.));
%put Number of logins: &NumberOfLogins.;

%macro _CreateLogin;

%do J=1 %to &NumberOfLogins;

%let Login = %scan(&Logins., &J, &Delimitor.);
%CreateLogin(_Login=&Login.);

 %end;

%mend;

%_CreateLogin;
