I am trying learn how to use the _vfp.setvar() method to create variables on the main vfp application object that can be accessed from any form using the _vfp.eval() method.

I am having trouble understanding the scope of the _vfp.setvar() calls...

If I create the object variable using _vfp.setvar() in my main .prg file (before any forms are called), they seem to be "public", in that any of the forms that might be launched can access the variables using the _vfp.eval() method.

However, if I create a new variable (call it "nEmployee")using _vfp.setvar() from within a form, and then close that form, and open another form, and try _vfp.eval("nEmployee"), it says that variable does not exist.

Basically I want a way to create and set publicly available variables to exchange data between forms. I thought this might be a good way. And it is... as long as you make the _vfp.setvar() call from the main .prg file.

Perhaps someone can teach me a better way to achieve this.
