How Do I Implement ---prompt 'Enter 1 To Continue Or CTRL C To Abort

Hi Guys, I have a SQL block which I want to run based on some values in the DB
-----------------
I am implementing the check as follows..
---------------------
PRINT 'Checking the DATABASE name and Schema Version '

SET NOCOUNT ON
CREATE TABLE chkversion (table_name VARCHAR(30), id INT, reason varchar(200))
GO

DECLARE @MSG CHAR(1)
print @MSG
GO

/* Make sure user is running the right script and right db user */

declare
@ver varchar(100),
@username varchar(100),
@cnt int
begin
select @ver = value from propertytable where id = 33086
select @cnt = count(*) from propertytable where parentid=5001 and propertyid = 726;
select @username = db_name(dbid)from master.dbo.sysprocesses where status ='runnable'
insert into chkversion (table_name, id, reason) values ('', -1, 'You are logging on Database - ' + @username)
insert into error_report (table_name, id, reason) values ('', -1, 'Your agile database version is ' + @ver)
if (@ver != '9.0.144'or @cnt !=0) begin
insert into chkversion (table_name, id, reason) values ('', -1, 'STOP: Your Schema Version and/or database version are not at original 90SP2. Please abort!')
end
else
insert into chkversion (table_name, id, reason) values ('', -1, 'PROCEED: You can run this script to upgrade your db schema from 9.0.144 to 9.0.178')
end
GO

DECLARE @MSG CHAR(200)
SELECT @MSG = convert(varchar(255), reason) from chkversion where id = -1
print @MSG
GO


DECLARE @MSG CHAR(1)
print @MSG
GO
SET NOCOUNT OFF
----------------------------------------------------------
After this, I want user to press 1 to continue or CTRL +C to abort based on the output message from above.
How Do I implement this feature?
In Oracle, I use...
Accept agproceed number prompt 'Enter 1 to continue or CTRL C to abort.';
