Why is the assignment fonts.enc.reencodings = reencodings and not the other way round? Similar definitions in the same file use more "logical" looking assignments like e.g. "local setups = fonts.protrusions.setups" 2. How does it work? Why is the local table variable "reencodings" in the function specialreencode able to retrieve values stored later in fonts.enc.reencodings? -- Ulrike Fischer ___________________________________________________________________________________ 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 ___________________________________________________________________________________
