getResources allows you to set the value of  global variables.
You must know the type and set DBF_xxx properly. The most common usage
is to override one of the EPICS_xxx variables. ALL of these variables are of
type DBF_STRING. getResources has code to check for EPICS_ and print an
error message if you attempt override it with the wrong type of data.
The error message is misleading. It will be changed in the next release.
I will also add info to the App Dev Guide describing each EPICS_xxx
parameter. Note that the ioc command epicsPrtEnvParams will display
the values of each of the EPICS_ variables.

Yes it is. I will ask Ken Sidorowicz to send info about how to order it.
Note that if you obtain a statically linked version of GDCT you do not need
any license.
