Subject: Re: Setting macro value from commandline

When starting a soft IOC you can set the value of iocsh variables from shell environment variables using the epicsEnvSet iocsh command like this:

epicsEnvSet(KEITHLEY2400_ETHERNET, "$(KEITHLEY2400_ETHERNET=164.54.49.10:4001)")



So, if you start the IOC like this:
./st.cmd
the iocsh KEITHLEY2400_ETHERNET variable will be set to 164.54.49.10:4001

but if you start the IOC like this:
KEITHLEY2400_ETHERNET=192.168.1.2 ./st.cmd
the  iocsh KEITHLEY2400_ETHERNET variable will be set to 192.168.1.2 

The '=' part to supply a default value can be omitted if you like.
