# Special cases
## Maximum number of decimal places
```sas
proc print data=work.temp maxdec=2;
run;
```
## labels in SAS
#### Rules for labels
1.Cant perform operations with lables.
2. Its only for display.
3. But it changes the **dataset properties**.
#### Defining single lables
```sas
proc print data=work.test;
label salary='annual salary`;
run;
```
#### Defining multiple labels
```sas
proc print data=work.test;
label salary=`annual salary`;
rating=`new rating`;
run;
```
#### Printing labels
```sas
proc print data=work.test;
label x=`new x`;
run;
```
```sas
proc print data=work.test;
var x;
run;
```
This will throw an error as you can not print or operate on labels. They are only for display.
## page size
```sas
options ps=10;
```
## list size
```sas
options ls=10;
```
#### Using page size or list size
```sas
options ps=10;
options ls=10;
proc print data=work.test;
run;
```
