I also wanted to see what I was sending to Exec, and was confused by the PRINT limit. Had to write a proc to print in chunks.

CREATE PROCEDURE [dbo].[KFX_PrintVarcharMax] 
    @strMax varchar(max)
AS
BEGIN
    SET NOCOUNT ON;

    DECLARE 
        @index int = 0,
        @start int = 1,
        @blkSize int = 2000;


    WHILE @Start < LEN(@strMax)
    BEGIN
        IF @start + @blkSize >= LEN(@strMax)
        BEGIN
            -- If remainder is less than blocksize print the remainder, and exit.
            PRINT SUBSTRING(@strMax, @start, @blkSize)
            BREAK;
        END
        -- Else find the next terminator (beyond the blksize)
        SET @index = CHARINDEX(CHAR(10), @strMax, @start + @blkSize);
        if @index >= @start
        BEGIN
            PRINT SubString(@strMax, @start, @index - @start + 1)
            SET @start = @index + 1;
            SET @blkSize  = CASE WHEN @start + 2000 < LEN(@strMax) THEN 2000 
                            ELSE LEN(@strMax) - @start + 1 END
        END
        ELSE
        BEGIN
            -- No char(10) found.  Just print the rest.
            PRINT SUBSTRING(@strMax, @start, LEN(@strMax))
            BREAK;
        END 
    END

END
