In this manual, we use Usually, programs are written and documented in English, and use English at execution time to interact with users.
This is true not only of GNU software, but also of a great deal of proprietary and free software.
in evaluating the variable named, but doesn't print the result returned.
This can be useful when a variable is bound to a sub-routine or object method which you want to call but aren't interested in the value returned.
By , one refers to the operation by which a program, or a set of programs turned into a package, is made aware of and able to support multiple languages.

Variables may be assigned the values of other variables, unquoted numbers (2.718), literal text ('single quotes') or quoted text ("double quotes").
In the latter case, any variable references within the text will be interpolated when the string is evaluated.
Also, this supplemental documentation might also help programmers, and even curious users, in understanding how GNU Two long words appear all the time when we discuss support of native language in programs, and these words have a precise meaning, worth being explained here, once and for all in this document.
The words are instead, quoting the first and last letter of each word, and replacing the run of intermediate letters by a number merely telling how many such letters there are.
But in this manual, in the sake of clarity, we will patiently write the names in full, each time…
They have no confidence at all that the dream might ever become true.
Yet some have not lost hope, and have organized themselves.
