hi guys i need to merge two tables in Sas

but with a condition like in a sql merge statement:

```
MERGE INTO TABLE_NAME USING table_reference ON (condition)
WHEN MATCHED THEN
UPDATE SET column1 = value1 [, column2 = value2 ...]
WHEN NOT MATCHED THEN
INSERT (column1 [, column2 ...]) VALUES (value1 [, value2 ...

```

there is somthing like that?

in case there isn't can you tell me how can i make this kind of append with condition ?
