As long as the public variable is only used for this, and it could never
be anything else, you'll not find problems. It isn't something I recommend.
It can be faster than a loop of _Screen.forms(). If you make it public
at the get go (in your main prg), you could use the Try/Catch method Ed
mentioned.
try
ShowData.mymethod(...)
catch
do form ...
endtry
There's plenty of ways to accomplish the task.
Good luck with it,
Tracy
