T-SQL (SS2K8) :: Write Into A Table User-entered Value And Increment That Number N Times As Existing Rows

I need to have a script where it ask the user for a value, the script will search for all records that match the value. Then it will display the numbers of records found and ask the user to enter a different value. The rest of the script will use this new value and increment by 1 n times as the number of records found. I started the script where it will ask for "HANDLE" and display the number of records found with that "HANDLE"

declare @HANDLE as varchar(30)
declare @COUNT as varchar(10)
declare @STARTINV as varchar(20)

set @HANDLE = ?C --This is the parameter to search for records with this value
set @STARTINV = ?C --User will input the starting invoice number
SELECT COUNT as OrderCount FROM SHIPHIST
where HANDLE = @HANDLE

I just can't figure out how to proceed to use the entered invoice # and increment by 1 until it reach the number of records found.

This will be the end results:

Count=5 --results from query
STARTINV=00010 --Value entered by user

Handle,Inv_Num
AAABBB,00010
AAABBB,00011
AAABBB,00012
AAABBB,00013
AAABBB,00014
