T-SQL Function to get ASCII values of characters stored

I am using a T-SQL block to get the dump of ascii characters stored in a database column. I know this is accomplished easily in Oracle using the DUMP() function. I am not taht familiar with SQL Server sytax, but I am using something like this.

    SET NOCOUNT ON
-- Create the variables for the current character string position 
-- and for the character string.
DECLARE @position int, @string char(15), @output char(1000), @output2 char(2000)
-- Initialize the variables.
SET @position = 1
SET @output2 = 'Start:'
SELECT @string = name from 
location where location_type = 4405 and owner_id = 362
and location_id = 53183
WHILE @position <= DATALENGTH(@string)

       BEGIN
       SELECT @output = CAST(ASCII(SUBSTRING(@string, @position, 1)) AS CHAR)
        + ' ' +      CHAR(ASCII(SUBSTRING(@string, @position, 1)))
        PRINT @output
        --SET @output2 = @output2 + '=' + @output
        SET @position = @position + 1
       END
        --PRINT @output2 
    SET NOCOUNT OFF
    GO

For some reason if I uncomment the code that relates to @output2, it won't print @output2 correctly. The idea is to get all the ascii values returned as a single line instead of getting a line for each character. Am I doing something wrong?

If you're looking for a single row this is probably the easiset way to go (building on Cyberkiwi's answer)

DECLARE @string char(15),
@output1 varchar(1000),
@output2 varchar(1000)

SELECT @string = name
from  location
where location_type = 4405 and owner_id = 362
and location_id = 53183

SET @output1 = ''
SET @output2 = ''

select 
    @output1 = @output1 + SUBSTRING(@string, number, 1) + ', ', 
    @output2 = @output2 + cast(ASCII(SUBSTRING(@string, number, 1)) as varchar) + ', '
from master..spt_values
where type='p' and number between 1 and LEN(@string)
order by number

PRINT @output1
PRINT @output2

Change the data types for @output and @output2 to varchar. Replace DataLength with Len. Char is fixed length and does not grow when you add strings at the end of the string.
