You will have to write your own formatting function to compute linebreaks. Under Mathematica 3.0 and 4, the TeXForm[] function is capable querying the front end for line break information, provided that the kernel is being run from the front end and that the expression supplied by the user is a box form or a Cell expression with box form contents. Let's say that I wanted to take the result of Expand[(x + y)^20] and format it with TeXForm[]. The syntax for doing this would be TeXForm[ToBoxes[Expand[(x + y)^20]]] If you were writing this to a file, you could also do: ToString[ToBoxes[Expand[(x + y)^20], TeXForm] The front end computes the line breaks based on the default font sizes and format types defined by your style sheet or inherited from global values. If you want greater control over this, you can do something along the lines of: ToString[ Cell[ BoxData[ToBoxes[Expand[(x + y)^20], TraditionalForm]], FontFamily -> "Times", FontSize -> 14, PageWidth -> 640 ], TeXForm ] If your windowing environment provides TeX Computer Modern fonts so that they can be used in notebooks, you can specify that this font be used at the size used in your TeX documents, and the linebreak calculations will be pretty much on target. Note that there are several macros that are emitted by the output of TeXForm. You can find definitions for these macros in notebook.sty, which appears on the Mathematica CD-ROM. -- P.J.
