Can I use environemnt variable as host in inputs.conf of forwarder ?

[parth_jec]

Is it possible in inputs.conf in windows machine to use

host=$

I tried using:
host=$computername

but in the indexer the events show 'host=$computername' and not the value of $computername

host = $COMPUTERNAME worked for me on the Windows Splunk 5.0.4 Universal Forwarder.
