GNU smalltalk command line interpreter

Hello,
I have a real dummy question! Beside other "smalltalks" I actually tried
GNU Smalltalk under OpenSUSE 10.3 on an AMD XP Machine:

localhost:~> gst -v
GNU Smalltalk version 2.1.12
Copyright 2003 Free Software Foundation, Inc.

COPYING.

Using default image path: /usr/share/smalltalk

The GUI (gst -qK browser/Run.st) works as usual for smalltalk." 'Hello,
world' printNl" in the worksheet gives the expected output in the
transcript window. I tried the example of the Tutorial
(http://www.gnu.org/software/smalltalk/manual/gst.html#Getting-started)
in the line interpreter as well (or is it not a command line interpreter?):

localhost:~> gst
GNU Smalltalk ready

st> 'Hello, world' printNl
st>                    

But as one sees from that copy there happens absolutely nothing! That is
also true for "123456 printString",  "6 + 7"  and other trial inputs. If
this is not a line interpreter I argue that it is only possible to start
files with a "shebang" or “sharp-bang”?

Where is may error?

Thanks in advance for help and best regards

Bernhard

The tutorial only works for GNU Smalltalk 3.0.x; the usability of the
command-line interpreter improved a lot in 3.0 in different ways:

1) each statement is evaluated separately and variables persist until
you type a bang (exclamation mark).  In 2.x each bang-separated chunk
would be a single evaluation unit.  If you want more statements to act
as single evaluation units in 3.x, wrap them with "Eval [ ... ]"

2) periods are implied at the end of a line if the grammar allows that

3) temporary declarations are optional.

4) the output is actually printed using #printOn: and not by some crappy
C code. :-)

Examples:

   #(1 2 3)!
   2.x => Array new: 3
   3.x => (1 2 3)

   a := 10 factorial
   b := a negated
   2.x => error (variables not declared, missing period before "b", etc.)
   3.x => 3628800 -3628800

I suggest that you download 3.0.1 and install it, or that you wait 10
days since on March 8th you could get the first release with support for
Seaside. :-P

Paolo

Included.  "gst-load --start Seaside" :-)
