Syntax

%label: macro-text

label

specifies a SAS name.

macro-text

is a macro statement, a text expression, or constant text. The following examples illustrate each:

```
 %one: %let book=elementary;
```
```
%out: %mend;
```
```
 %final: data _null_;
```

Details

The label name is preceded by a %. When you specify this label in a %GOTO statement, do not precede it with a %.
An alternative to using the %GOTO statement and statement label is to use a %IF-%THEN statement with a %DO group.

Example

Example 1: Controlling Program Flow

In the macro INFO, the %GOTO statement causes execution to jump to the label QUICK when the macro is invoked with the value of short for the parameter TYPE.

%macro info(type);
   %if %upcase(&type)=SHORT %then %goto quick; /* No % here */
      proc contents;
      run;
      proc freq;
         tables _numeric_;
      run;
   %quick: proc print data=_last_(obs=10);     /* Use % here */
      run;
%mend info;

%info(short)

Invoking the macro INFO with TYPE equal to short generates these statements:

PROC PRINT DATA=_LAST_(OBS=10);
   RUN;
