Solution 2

use IsNull[^] to replace the null value with a specified value

SQL

SET @ASACCRUED = isnull( @ASACCRUED,0)+@MMINTR

Solution 3

--Assume if @MMINTR = 1
--if @ASACCRUED is null
DECLARE @ASACCRUED INT = 1,
@MMINTR INT = NULL

SET @ASACCRUED = IIF( @ASACCRUED IS NULL, 0 , IIF( @MMINTR IS NULL, 0 , @ASACCRUED + @MMINTR ) )
SELECT @ASACCRUED

IIF is non-standard SQL that only appears in SQL Server up to 2008 and then again from 2012. It's only included for Access compatibility and is actually translated to a CASE statement anyway. It only works with SQL Server and is not portable to other platforms.
But even CASE is a bit of a long-winded way of approaching this problem. ISNULL is the most efficient, COALESCE would be the next best
