• Microsoft PowerPoint 98 Macintosh Edition
• Microsoft PowerPoint 97 For Windows

SUMMARY

This article contains a sample Microsoft Visual Basic for Applications macro (Sub procedure) that finds all objects in the active presentation and applies an entry custom animation to each one. The macro randomly chooses which animation effect to apply to each object.
