How to set ISM build environmnet(MMSearchPath)

[fanasus]

So far, I need use commandline to build the ims project with installshield 9 or above. before build, I need set MMSearchPath dynamically. Currently, for setting it, I change the registry value with little application: e.g
HKEY_CURRENT_USER\Software\InstallShield\Developer\9.0\Project Settings
MMSearchPath=...

I want to know:

whether there is another way to set MMSearchPath dynamically, like PATH setting(set PATH=%PATH%;....)?

Thanks.

ISCmdBld takes a -o argument for passing the merge module path in.
