Hi, Typeset this file :) \starttext The file \filename{knuth} contains a quotation from Don Knuth, the creator of \TEX. \stoptext core-ver.tex defines \filename to be \unexpanded\def\filename#1{{\tttf\hyphenatedfile{#1}}} and supp-lan.tex defines \hypenatedfile to be \let\hyphenatedfile\hyphenatedurl However this is redefined in supp-box.tex, due to which \filename gets redefined. %D \macros %D {hyphenatedword, %D hyphenatedpar, %D hyphenatedfile, %D dohyphenateword} %D %D The next one is a tricky one. \PLAIN\ \TEX\ provides %D \type{\showhyphens} for showing macros on the terminal. When %D preparing a long list of words we decided to show the %D hyphens, but had to find out that the \PLAIN\ alternative %D can hardly be used and|/|or adapted to typesetting. The next %D two macros do the job and a little more. Although, I cannot gather this from the definition, it seems that \hypenatedfile is showing all the hyphens in a file. One of the macros need to get a different name :) Aditya
