Hi there,

from hansl-primer p. 36 it is clear there are no global variables.

Is there any way to circumvent this? For example by using default options defined outside the function body and passing them with pointers to the function body? I would like to have a function to “set” some global options for the plotting package I am working on. However, to do so, I need to define a kind of global container (a bundle, e.g.) with the default values, upon which the function can then work (a) and whose values I can also load, say as defaults in the function header, to other functions (b). Finally (c), is there an option to define pointer-type string variables and pass pointers to a string?

Best
