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
- A character string literal and one of its options, for example, "City/State/Zip":U
It
also follows the EDITING keyword in an EDITING phrase and is a device
delimiter in Windows.
See :: Punctuation for
rules to help you decide whether to use period, colon, or double
colon syntax.
