SAV for Linux: How do I set the DWORD value to zero?

According to page 28 (right-hand column under "Description") of "SymantecTM AntiVirus for Linux 1.0.14 Implementation Guide", it says:

By default, the maximum number of items that can be added to a manual scan that is generated from the command line interface is 100. You can use symcfg to change the DWORD value \Symantec Endpoint Protection\AV\MaxInput to increase this limit. To remove the limit entirely, you must set it to 0.

I wish to remove the limit entirely, that is, I need to set it to 0.

Could someone be kind enough to give me the specific commands that I must issue at the terminal window? I am using Ubuntu 12.10, 64 bit, English, kernel version 3.5.0.21.

Thanks in advance.
