Case statement

Is it possible to have multiple expressions, or dml expressions in a case
statement similar to the following?
DECLARE @.path_f1 nvarchar(200)
DECLARE @.path_f2 nvarchar(200)
SELECT
@.path_f1 = output_path_file1,
@.path_f2 = output_path_file2
FROM t1
WHERE t1id = 1
SELECT
CASE
WHEN f1_status = 0 THEN
UPDATE t1
SET f1_status = 1, f1_created = getdate()
WHERE t1id = 1
EXEC usp_t1 @.path_f1, null
WHEN f1_status = 1 AND f2_status = 0 THEN
UPDATE t1
SET file2_status = 1, file2_created = getdate()
WHERE t1id = 1
EXEC usp_t1 @.path_f2, null
ELSE
RAISERROR ('Error Message', 16,1)
END
FROM t1
WHERE t1id = 1

Not the way you're doing it. You can have something along the lines of:
UPDATE t1
SET
f1_status = CASE
WHEN f1_status = 0 THEN 1
ELSE f1_status END
, f1_created = CASE
WHEN f1_status = 0 THEN getdate()
ELSE f1_created END
WHERE t1id = 1

|||The issue would become very straightforward and simple only if one stops
using the phrase 'a CASE statement' because there is no such a thing, and
starts using 'a CASE expression.'
