However, we do accommodate entering numbers using the locale decimal character in GUI dialog boxes that want numerical input. I'm not sure if this is the context that the original poster had in mind, but I've noticed that we were not accepting the decimal comma in the dialog box that is offered when you call a packaged function. That is, suppose a function has a scalar argument; then a "combo" box will be offered in which you can select a scalar variable (if any are defined), or type in a number. It seems reasonable that we should accept the decimal comma here, so I've made a change in gretl CVS to that effect. Allin.
