Now, when we have a solid grasp of the global statements timing habits, let’s look at the coding techniques allowing us to take full control of when and whether global statements take effect (executed). In the latter case, it is compiled with the PROC step, then immediately executed before PROC step’s execution. In the first case, the stand-alone TITLE statement is compiled on its own and immediately executed thus setting the title for the PROCs that follow. That is because the LIBNAME global statement took effect (executed) right after the DATA step compilation before its execution.įor the same reason, you can place global statement TITLE either in open code before PROC that produces output with a title or within that PROC. NOTE: The data set OUTLIB.CARS has 428 observations and 15 variables.Īs you can see, not only our LIBNAME statement “executed” (or “took effect”) despite the IF-THEN condition was FALSE, it successfully assigned the OUTLIB library and applied it to the data OUTLIB.CARS statement that appears earlier in the code.

NOTE: There were 428 observations read from the data set SASHELP.CARS. NOTE: Libref OUTLIB was successfully assigned as follows: Try sticking it in there and SAS will slap you with an ERROR: IF expression THEN executable- statement1 They are so not executable, that they even syntactically cannot be a part of the IF-THEN/ELSE statement that executes DATA step statements depending on specified conditions: Even though SAS global statements can appear in DATA steps, they are not executable by definition. I know, the title of this blog post may sound like an oxymoron.

Here are the most used global statements: They can be used in open code, within macros, as well as within DATA and PROC steps.

They take effect as soon as SAS compiles programming statements and persist during the entire SAS session or until another global statement overrides them. SAS global statements define certain SAS objects and set values for system options.
