Schemas

[Alan Davey]

Hi Martin,

The () don't have anything specifically to do with a "Do" command.  These
have been Omnis' way of referencing the associated thing via notation since
at least Omnis 7.

Run the following from any class (window, menu, object, etc) you have:
Ok message {[$cclass.$name]}
Ok message {[$cclass().$name]}

The first will return '$cclass' and the latter will return the actual name
of your class.

In other words, the first will return the name of the property $name is
attached to ($cwind, $cobj, etc), while in the second case it returns the
name of what $cclass is currently associated with.

HTH,

Alan
