How to invoke the mc shell in order to change shmem variables
-------------------------------------------------------------
login as iota on iota17


You must go to iotamc and type 

source SOURCEME

Then go to lmt/mc directory and type

mc_jshell jni

for access to the shared memory used by the system.

When you get the command prompt (be patient) type ? or help
to see a list of commands.  There will first be a list of 
all the objects that are available, then a list of some useful
aliases for these things that make more sense.  Most of the
object names correspond well to things that you know about
in the system.

just typing the name of the object will give a list of all
the shared memory data ... except for data that are in arrays.

you can also retrieve this data with get cmdname.

values may be set by entering the command name followed by
the keyword/value pair you wish to set.  e.g. 

widget -command on

This is just scratching the surface obviously......
