Similar to what Lowell already posted, but leaving values as variables.

DECLARE @a AS INT = 1;

DECLARE @b-2 AS INT = 1;

DECLARE @Parameter1 AS INT;

DECLARE @Parameter2 AS INT;

DECLARE @Parameter3 AS INT;

DECLARE @Parameter4 AS INT;

SELECT @Parameter1 = Par1,

@Parameter2 = Par2,

@Parameter3 = Par3,

@Parameter4 = Par4

FROM( VALUES(1, 0, 77, 14, 21, 0),

(1, 1, 77, 14, 0, 0),

(1, 2, 77, 14, 0, 0),

(1, 3, 77, 14, 21, 0),

(1, 4, 77, 14, 21, 0),

(0, 0, 68, 14, 0, 0),

(0, 1, 78, 14, 21, 0))PM(A,B,Par1,Par2,Par3,Par4)

WHERE A = @a

AND B = @b-2;

SELECT @Parameter1 AS Par1,
