I do mean the (missing) context of the text to be translated. It can be a header of a manual, it can be a banner, it can be an error text, and so on.
Do you have a matching sentence, i.e. context, or otherwise a technical context? Translating is not just a matter of translating words. The context should make clear how to interpret the specific text, when there may be mote than one match. The word "Using" may be more difficult than "library".
For the L of the DLL I'll probably use IBM's translation ("module"). In OS/2's Dutch a library is what you'll find in the x:\OS2\HELP subdirectory. To show a case where context could matter, "HELP LIBPATH" produces (translated):
dynalink-library
DLL-module
DLL
DLL-file
OSO001H.MSG contains (I didn't check the whole file):
module
dynamic-link-module
So almost a library of choices, but the point is that the option "library" is missing. Dynalink-library occurs twice, but that's a rather unusual word. Anyway, I want context of the whole "Using ..."-part. To avoid the introduction of animals when it's raining cats and dogs in English, while it's raining pipe handles in Dutch. For example, embed it in a sentence or story. Like "(I am) Using (the) ... library (at the moment)". Or "(Manual, Chapter 2,) Using ...". The clarifying context may influence what's right, or better.
