referencing values in input

[dschwoerer]

The documentation says it is possible to reference values in the input file.

However, that is only true for numerical values.
For string values, that is not possible.

It would be nice to add the functionality to reference other values, however I am not sure what syntax should be used.

a = "some_file.nc"
b = :a
b = `a`
b = ???

Any opinions?

Simple uses should be ok e.g.

b = a

(or other simple lookup like b = mesh:name)
but if we want to do more complicated things like string concatenation

b = a + "_something"

then the parser will need to be more complicated: Every expression has BoutReal type currently.
