Syntax for Rename

I'm using a command button to rename files and I need the syntax for the "=" sign and for " " spaces.

Rename PATTERN="=" TO="~" FINDREP
Rename PATTERN=" " TO=" " FINDREP
Rename PATTERN=" " TO=" " FINDREP

Change the = sign to nothing
Change 3 spaces to 1 space
Change 2 spaces to 1 space

There's no special syntax for those - did you try it? What you have there will work fine.
