As Jim said, your code may blow up, if e.g. you use it within menu procedure. However, it's not necessary to use Activeform, and sometimes it's not applicable (maybe you want to call form which is not active currently). The 100% solution can be accomplished by 2 ways:
1. Link form to external object property
Do Form Myform Name oApp.myform LINKED
or
2. Search through _SCREEN.Forms collection to get correct reference.
