Oops... made one stupid mistake...
Please read as "right after READ EVENTS store .F."

> ...
>Before call READ EVENTS command in your first APP, define that public variable and store .T. to it, and right after CLEAR EVENTS store .F.. In another APP you may check that variable as follows:

If Type( "_READEVENTSINEFFECT") <> "U" And _READEVENTSINEFFECT
>    && READ EVENTS command is issued
>Else
>    && no READ EVENTS in effect
>EndIf

>Hope this helps.
