The +%D control sequence \type{\height} on the other hand uses only +%D one. Knowing this, we can improve the performance of \TEX, +%D both is terms of speed and memory usage, by using control +%D sequences instead of the words written in full. +%D +%D Where in the \ASCII\ file the second lines takes nine extra +%D characters, \TEX\ saves us 13~tokens. +%D +%D \starttyping +%D \hrule width 10pt height 2pt depth 1pt +%D \hrule \!!width 10pt \!!height 2pt \!!depth 1pt +%D \stoptyping +%D +%D One condition is that we have defined \type{\!!height}, +%D \type{\!!width} and \type{\!!depth} as respectively +%D \type{height}, \type{width} and \type{depth}.
