Here's a concrete use in a code comment of the word bound.

Though the present tense bind might be the proper grammar in this specific context.

$ sed -n '254,257p' utils.tcl
    # If the window is not mapped, it may have any current size.
    # Then use required size, but bound it to the screen width.
    # This is mostly inexact, because any toolbars will still be removed
    # which may reduce size.
$
