Hi Joe, optional arguments, denoted by name___ will do the trick. E.g. foo[p_,q_,opts___]:= Module[ {bar}, bar=Table[ f[x,y], {x,1,p},{y,1,q} ]; ArrayPlot[bar,opts] ] If you have options for different functions, may be you want to use the function FilterOptions form the package: Utilities`FilterOptions` Daniel Joe Christy wrote: > I have a function implemnted as module which uses various builtin > functions.
