This would have to be defined inside the package for each function. Presumably something like this: f[x_] := x^2 f /: SyntaxInformation[f] = {ArgumentsPattern -> {_}}; SyntaxInformation[f] {ArgumentsPattern->{_}} ?? f Bob Hanlon ---- "Nasser M.

Except I am finding that SyntaxInformation[] only works on functions in System context. So I can't find it to determine which is a function and which is not for functions in other packages (i.e. outside the kernel). So I have to resort to the old method for determining which Symbol is a function or not for those. Compare the result for something not in the kernel with something outside: Needs["Combinatorica`"] SyntaxInformation[AddEdge] {} SyntaxInformation[Cos] {ArgumentsPattern -> {_}} Even though AddEdge IS a function, I was expecting it to return the ArgumentPattern-> ..... list, but it did not. Is SyntaxInformation[] only supported for kernel functions? (i.e. in System`) (may be because those packages do not have support for it added?) --Nasser
