Hi, How can I make \framed ignore the width of the rule? I am trying to typeset internet protocol headers, but I cannot fully get what I want. Here is my attempt: \unprotect \makecounter{v!protocolheaderlength} \defineframed[protocolfieldheader] [location=lohi,height=3\lineheight,offset=none,strut=yes] \def\startprotocolheader {\dodoubleempty\dostartprotocolheader} \def\dostartprotocolheader[#1][#2]% {\getparameters[c!protocol][#1]% \let\field\protocolheaderfield \resetcounter{v!protocolheaderlength}% \vbox\bgroup % \ruledvbox\bgroup \removeunwantedspaces \dontleavehmode \protocolfieldheader[frame=on,width=\c!protocolbits\c!protocolunitsize]% {\let\\\crlf\bold #2}\crlf} \def\stopprotocoloheader {\egroup} \def\protocolheaderfield#1#2% {\doif{\countervalue{v!protocolheaderlength}}{\c!protocolbits} {\resetcounter{v!protocolheaderlength}\crlf}% \removeunwantedspaces \dontleavehmode \protocolfieldheader[width=#1\c!protocolunitsize]{\let\\\crlf #2\\(#1)}% \incrementcounter{v!protocolheaderlength}{#1}} \protect % \showstruts % \showboxes \starttext % Why should unitsize=1mm. Are things being scaled by another factor? \startprotocolheader[bits=16,unitsize=1mm][General MAC Headers] \field {1} {HT} \field {1} {EC} \field {6} {Type} \field {1} {ESF} \field {1} {CI} \field {2} {EKS} \field {1} {Rsv} \field {3} {LEN MSB} \field {8} {LEN LSB} \field {8} {CID MSB} \field {8} {CID LSB} \field {8} {HCS} \stopprotocoloheader \stoptext Notice that all the lines are not of the same size. It seems that the rules of framed are causing the frame to be of a larger width. Also am I missing a scaling factor in width= expressions above. Everything looks fine with unitsize=1mm, but the final figure is clearly larger than 16mm. I am confused as to what is happening. Is there any better way to do this? Thanks, Aditya
