strsub is not working on Windows 7

[sireesh]

Hi Experts,

I am facing an issue with strsub command in my batch file.When I am running the below command from the batch file :

strsub -s -d *.sql #WWF_USER# current_user

I am getting the below message

'strsub' is not recognized as an internal or external command,

operable program or batch file.

What should I do to fix this. The same batch file is running fine on the Windows 2003 server.

Please let me know if there is any patch that I should apply to overcome this issue.

Note: I have cygwin and perl installed in my system.

Regards
