Re: Parameter from one form to another form

Unless I am missing something... Forms to Forms parameters do not need global parameters - the sending form needs to create a parameter list and pass it and the receiving form needs to read the parameter list. None of which needs to be global. Globals will work fine, if that is what you want to use.

If there is something I am missing in the question - perhaps Designer/2000 to Forms is different than forms->to<-forms, I apologize. If I am correct, just look at the on-line help for creating parameter lists. Works easy enough.
