Re: Plugins and referencing *variables* in the loading program

[Maarten Boekhold <boekhold at emirates dot net dot ae>]

Hi Brian,

Don't know if you noticed, but the thread you are referring to was 
started by me as well :) All the material discussed in there I managed 
to apply just fine.

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...
