Question Exact meaning of the "world" in "hello world"
Hello!

I have a question to native English-speaking people. In the popular program's "hello world" greeting, what meaning the "world" has: "all", "everybody", "people", "friends" or "whole world", "planet", "Earth", "Universe"?

In other words, to whom this greeting is addressed: to the people capable to see program's output, or to the whole world or whole Universe?

Here in Russia, "hello world" is usually translated as "привет, мир" that means the "hello whole world", "hello Universe" or "hello planet". I'm afraid that the correct meaning should be like "hello all", "hello everybody", "hello people" or similar.

I tried to search in dictonaries but "hello world" is so common phrase so it is not explained. I'm afraid its meaning is trivial for every native English-speaking person. Smilie

Could somebody please explain?

Regards,
Eugene

plcalc_world

PLCALC_WORLD(3plplot)						    PLplot API						     PLCALC_WORLD(3plplot)

NAME

       plcalc_world - Calculate world coordinates and corresponding window index from relative device coordinates

SYNOPSIS

       plcalc_world(rx, ry, wx, wy, window)

DESCRIPTION

       Calculate world coordinates, wx and wy, and corresponding window index from relative device coordinates, rx and ry.

       Redacted form:  General: plcalc_world(rx, ry, wx, wy, window) Perl/PDL: Not available?

       This function is used in example 31.

ARGUMENTS

       rx (PLFLT, input)
	      Input relative device coordinate (ranging from 0. to 1.) for the x coordinate.

       ry (PLFLT, input)
	      Input relative device coordinate (ranging from 0. to 1.) for the y coordinate.

       wx (PLFLT *, output)
	      Pointer to the returned world coordinate for x corresponding to the relative device coordinates rx and ry.

       wy (PLFLT *, output)
	      Pointer to the returned world coordinate for y corresponding to the relative device coordinates rx and ry.

       window (PLINT *, output)
	      Pointer  to the returned last defined window index that corresponds to the input relative device coordinates (and the returned world
	      coordinates).  To give some background on the window index, for each page the initial window index is set to  zero,  and	each  time
	      plwind(3plplot)  is  called  within  the page, world and device coordinates are stored for the window and the window index is incre-
	      mented.  Thus, for a simple page layout with non-overlapping viewports and one window per viewport, window corresponds to the  view-
	      port  index (in the order which the viewport/windows were created) of the only viewport/window corresponding to rx and ry.  However,
	      for more complicated layouts with potentially overlapping viewports and possibly more than one window (set of world coordinates) per
	      viewport,  window  and  the corresponding output world coordinates corresponds to the last window created that fulfils the criterion
	      that the relative device coordinates are inside it.  Finally, in all cases where the  input  relative  device  coordinates  are  not
	      inside any viewport/window, then window is set to -1.
