Can I have Exec(...) statements within a transcation ?

Is the following T-SQL correct, in which I am trying to make sure that th effect of 3 stored procedures gets reversed in case of an error ? I know if in place of stored procedures I had action queries like 'ActionQry1', 'ActionQry2' and 'ActionQry3' then the transaction logic would work. But will it work even if exec(...) statements are there in the transaction ? Each stored procedure is made up of an action query.

begin tran
exec("storeprocedure1('2')")
if @.@.error=0
begin
exec("storeprocedure2")
if @.@.error=0
begin
exec("storeprocedure3(122)")
if @.error=0
commit tran
else
rollback tran
end
else
rollback tran
end
else
rollback transure, exec statements will work,
but your syntax is not correct, it should be like this:

 begin tran
 statement1
 if (@.@.error <> 0)
 begin
 rollback tran
 return
 end
 statement2
 if (@.@.error <> 0)
 begin
 rollback tran
 return
 end
 commit tran
