However, that thread deals with importing *functions*, not variables. I created a stand-alone test in which the plugin is trying to reference a *variable* in the loading program, and that *fails*. I can post my test program if anybody is interested... Maarten Brian Dessent wrote: > Maarten Boekhold wrote: > > >>suppose I have application A, that loads (gmodule_open) a module B.
