Script to edit all form names?

Script to edit all form names?

I have a collection of applications, each with several form names containing the string "easy":
EasyPlus
EasyBall
etc...

I'm wondering if there is some way (using a function or otherwise), to loop through all the form names in an application and replace part of the form name; in this case, each "easy" to "busy." So upon execute, the names of the forms above would change to:
BusyPlus
BusyBall
etc...

Thanks,
