Hi Hans, thanks for Your help, but I am sorry \usepath[...] \usesubpath[...] do not work in that way I thought. I start in /home/bmi/import/TestConTeXt/blocks/ with four files: demo.tex = the project-file eniro.tex = the enviroment student.tex = a data-file with two text-blocks test.tex = a work-file, which will use text-blocks from student.tex all things are pretty good -- in test.tex I can use the text-blocks from student.tex (student.tub). When I separate the dat-file = student.tex and the work-file work-file = test.text in different subdirs it ist not possible to use the text-blocks form student.tex in test.tex ~/import/TestConTeXt/blocks/data/student.tex with all help-files -- all things are ok ~/import/TestConTeXt/blocks/work/test.tex running texexec test.tex, no text-block from student.tex In file test.tmp: % test.top \unprotect \setupsystem[\c!gebied={/home/bmi/}] \setupsystem[\c!n=1] \setupsystem[inputfile=test.tex] \protect How have I to set up the path? \usepath[/import/TestConTeXt/blocks/] or \usepath[/home/bmi/import/TestConTeXt/blocks/] ??? \usesubpath[dat, work] or \usesubpath[dat/, work/] ??? I have no idea -- please give me a hint to stop my frustation! thanks Bernd
