assign a point variable to a specific point

I want to assign a point variable to a specific point - here is the point cooridinates:

The colon I am not sure what to do with it.

How do I assign this in VBA?

Dim myPoint As Point3d
myPoint.X = "120127:1.59600"
myPoint.Y = "119952:3.37943"
myPoint.Z = 0

Thanks,

Paul
