i am using 8.1.7
i didn't create any recovery catalog
i have the following script to backup the whole database

RMAN> run {allocate channel c1 type disk
format 'c:\backup\%U';
backup database inlude current controlfile;

Every time i have to run this script manually
1-C:\rman target sys/gateway@testdb /nocatalog
2-Write the script manually each time i want to take backup

I want to create a batch file which includes the script which i have to run manaully
So by creating a batch file we can schedule the task of Backup

For example look at the batch file which i had for export
exp.bat
exp 'sys/gateway@testdb as sysdba' owner=hr log=c:\log1.log

Like that batch file how can we create the batch file for rman backup
Can anybody help me in this regard?
Thanx in advance
