Hi,

I'm writing an batch file to create report

In the batch file iam passing two arguments:startdate and finishdate

Ex: startdate=07-sep-2009 finishdate=07-sep-2011

I need to have script that takes command line argument as input and gives me out currentdate last year and current date next year as mention above example.

currentdate-1 year & currentdate+ 1year

For example if I pass argument as 07-sep-2010 to batch script I should get ouput as startdate=07-sep-2009 finishdate=07-sep-2011.

Could any one please help?.

Regards,  
Anand
