presenting data in SAS

what are the different types of presentable formates in SAS for presenting the data,please explain me with some with some formates used in SAS.

Thanks Mr.Bansal for your kind reply.

Formats are used to output data in a formatted way.
e.g. as we know SAS stores date as numeric number i.e. number of days
from 01Jan1960.
So if you display date without formatting i.e.
put dt;
it will look like some thing -
18549

Which is bit difficult for user to calculate actual date from this number.
Now if you display it using format date9 e.g.
put dt date9.;
it will come out as 14OCT2010,which sounds much better.

There are number of formats,some of the most common formats are -
w.
w.d
$w
$charw.
DOLLARw.d
COMMAw.d
MMDDYY10.
DATE9.

where -
The w indicates the width (bytes or number of columns) of the
variable.
The d is used for numeric data to specify the number of digits to the right of the decimal place.
