Since you can execute commands in any window (or viewer in 
Oberon terminology, any viewer is also a kind of a shell. There is 
a kind of a meta command executing commands written in a viewer.

In A2/WinAos this meta command is: SystemTools.DoCommands and
It reads all commands until it encounters two ~ (possibly separated by 
white space). Normal commands terminate their parameters usually 
by a single ~.

I do not recall, how it was called in System 3 or System 4 and I was not able 
to dig it out quickly enough.

BTW: A surprisingly similar interface to execute commands was the worksheet 
user interface of the Macintosh Programmers Workshop on the classic Mac 
(see: https://en.wikipedia.org/wiki/Macintosh_Programmer%27s_Workshop) .
It is not so surprising if you know that the Oberon System and the classic Mac
both can be traced back to the heritage of the Xerox Alto at developed at PARC https://en.wikipedia.org/wiki/Xerox_Alto).

Programming for the Oberon GUI is very different to programming for 
Windows/Mac/*ix GUIs.
