your comment got through to webmaster - thanks for attending to it - ive a follow suggest
"all its input" is improper grammar - that should be "all of its input" also, i would either quote or hyphenate "the end of file string"; because that phrase is not merely descriptive - it is a very precise technical term, taken as a whole - just IMHO, but i would rather see something like one of these: the end-of-file string the "end of file" string the End Of File string
