And if there isn't one. Where I can found definitions of macros define in this file (like \dosingleargument and so on). syst-aux.mkiv (merge of syst-gen.mkii and syst-ext.mkii) Also I have another question. In file page-lay.mkii there is definition: \def\addpagecutmarks % #1 {\executeifdefined{\??ly:n:\c!marking:\@@lymarking}\gobbleoneargument} I don't understand this part: {\??ly:n:\c!marking:\@@lymarking}, especially I don't know what ":n:" does or means. Can someone briefly explain it to me? The 'n' is to distinguish between the values for ...cutmarks and ...colormarks \def\addpagecutmarks % #1 {\executeifdefined{\??ly:n:\c!marking:\@@lymarking}\gobbleoneargument} \def\addpagecolormarks % #1 {\executeifdefined{\??ly:c:\c!marking:\@@lymarking}\gobbleoneargument} Thank you for answer, I have just another question. On wiki in System macros/ Handling arguments (http://wiki.contextgarden.net/System_Macros/Handling_Arguments) are mentioned these macros: \dosingleargumentwithset \command[#1] \dodoubleargumentwithset \command[#1][#2] \dotripleargumentwithset \command[#1][#2][#3] \dodoubleemptywithset \command[#1][#2] \dotripleemptywithset \command[#1][#2][#3]I'm not sure but I think, that I read somewhere that these are old and obsolete. Is true or these macros are still in use and I just mistook it?ThanksTomas Pustelnik __________ Informace od ESET NOD32 Antivirus, verze databaze 5034 (20100416) __________ Tuto zpravu proveril ESET NOD32 Antivirus. http://www.eset.cz -------------------------------------------------------------------------------- ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________________ __________ Informace od ESET NOD32 Antivirus, verze databaze 5034 (20100416) __________ Tuto zpravu proveril ESET NOD32 Antivirus. http://www.eset.cz
