Code folding example on PHP code with Vim. Code or text folding, or less commonly holophrasting, [1] is a feature of some graphical user interfaces that allows the user to selectively hide ("fold") or display ("unfold") parts of a document.
A comma-free code is block code in which no concatenation of two code words contains a valid code word that overlaps both. [ 1 ] Comma-free codes are also known as self-synchronizing block codes [ 2 ] because no synchronization is required to find the beginning of a code word.
Some non-English language keyboards have special keys to produce accented modifications of the standard Latin-letter keys. In fact, the standard British keyboard layout includes an accent key on the top-left corner to produce àèìòù, although this is a two step procedure, with the user pressing the accent key, releasing, then pressing the letter key.
For this reason, Shannon–Fano codes are almost never used; Huffman coding is almost as computationally simple and produces prefix codes that always achieve the lowest possible expected code word length, under the constraints that each symbol is represented by a code formed of an integral number of bits. This is a constraint that is often ...
Linear block codes have the property of linearity, i.e. the sum of any two codewords is also a code word, and they are applied to the source bits in blocks, hence the name linear block codes. There are block codes that are not linear, but it is difficult to prove that a code is a good one without this property.

Although certain fields within the PSW may be tested or set by using non-privileged instructions, testing or setting the remaining fields may only be accomplished by using privileged instructions. Contained within the PSW are the two bit condition code , representing zero, positive, negative, overflow, and similar flags of other architectures ...
