The colon (:) symbol ends block labels and block header statements like DO, FOR, and REPEAT. It also serves as a separator between:
A handle reference and an attribute or method, for example
ttCust:PRIVATE-DATA or
ttCust:CLEAR( ), where
ttCust is a handle to a temp-table
An object or static type-name reference and a class-based property, method, or event, for example,
rObj:ToString( ),
rObj:NEXT-SIBLING, or
Progress.Lang.Class:GetClass( "Progress.Data.BindingSource" ), where
rObj is an object reference to a
Progress.Lang.Object instance
It also follows the EDITING keyword in an EDITING phrase and is a device delimiter in Windows.
