Thank you Mr.Ron. It worked like a champ. I just had it tweeked a little bit to suit my requirement. Yes. It is indeed an odd requirement to store a comboYear String.

DECLARE @BegYr INT = 2013

DECLARE @EndYr INT = 2015

DECLARE @Diff INT

SELECT @diff = @EndYr - @BegYr

DECLARE @E INT

DECLARE @a VARCHAR(10)

DECLARE @Z VARCHAR(10)

SET @E = @BegYr

IF @Diff = 3

BEGIN

SET @Z = (SELECT SUBSTRING(CAST(@E AS VARCHAR(4)),LEN(CAST(@E AS VARCHAR(4))),LEN(CAST(@E AS VARCHAR(4)))))

WHILE @E < @EndYr

BEGIN

SET @E = @E + 1

SET @a = (SELECT '/' + SUBSTRING(CAST(@E AS VARCHAR(4)),LEN(CAST(@E AS VARCHAR(4))),LEN(CAST(@E AS VARCHAR(4)))))

SET @Z = @Z + @a

END

SELECT @Z

END

ELSE

BEGIN

SET @a = (SELECT SUBSTRING(CAST(@BegYR AS VARCHAR(4)), 4, 1) + '/' + SUBSTRING(CAST(@EndYR AS VARCHAR(4)), 4, 1))

Select @a

END
