Global runtime strings help

[Jonathan Crapuchettes]

I'm working on an application that requires a large number of strings that only 
need to be loaded once at runtime and need to be accessible to all threads 
throughout the execution of the program. Some of these strings are variables 
like database host and username that need to be read from a file.

Can anyone help me with an example how they might do this task?
Thank you,
JC
