Chris, I had a similar problems with a package auto-saved from notebooks recently. In fact it was even stranger: I found that the packages worked fine with Mathematica on Windows but I got syntax errors when reading them into a Linux kernel (the same files from the same file system). I found that I could fix the problem by converting the package file to Unix format (changing the end-of-line characters. Finally I managed to track down the line where the error occurred: it was a usage message where I had typed something like func:usage="text of message" ; Note that I had typed a (useless but, I would have thought, harmless) space before the semi-colon. The line happened to be of a length such that it was broken when saved to give something like func:usage="text of message" \ ; and this was causing the problem. Eliminating the space fixed it. This was inside a big package and was not on the line number mentioned in the error message so it was hard to track down. Perhaps you have something similar in your file. I would call this a bug.

Hello, On loading a package file, Mathematica says it finds a syntax error on a certain line number (which I have located in emacs). Here is the relevant code snippet: Module[{stdexitout, xtemp}, stdexitout = {x, f, oldxL, oldfL, xL, fL, xU, fU, xmax, evalcount, evallimit, tol}; Which[fU T fL, stdexitout, xU == xmax, Message[MessageName[FindUnimodalMinimum, "unbound"]]; stdexitout, evalcount T evallimit, Message[MessageName[FindUnimodalMinimum, " evallimit"]]; stdexitout, True, xtemp = Min[(1 + a) xU - a xL, xmax]; boundunimodaldecision[x, f, xL, fL, xU, fU, xtemp, ReplaceAll[f, Rule[x, xtemp]], xmax, \ evalcount + 1, evallimit, tol]]]; In the package file, the indicated line (on or before where the syntax error occurrs, according to Mathematica) includes the following code: Message[MessageName[FindUnimodalMinimum,"evallimit"]];stdexitout,True, The entire module statement is correct syntax, or at least it evaluates without errors when executed in a notebook. What, if anything, should I do about this? Thanks, -- http://chris.chiasson.name/
