"1-orgin" means "starts at 1", as opposed to "0-origin", which means "starts at 0". This is a an old debate (does the first element of an array have index 1, as in Fortran, or 0, as in C?), with old terminology. The referenced code takes the the 1-origin column number from the error message, and subtracts 1 (to convert it it to 0-origin), before passing it to move-to-column (which expects a 0-origin column number). One can argue either way, but I think if the first line is line one, then the first column for consistency should be column one. The convention as currently implemented (but not documented!) in Guile is broken. --Per Bothner Cygnus Solutions bothner@cygnus.com http://www.cygnus.com/~bothner
