Hello everybody,

As I'm quite new to PostScript and having a problem I do not understand
I hope somebody experienced can help me.

Consider the following program:

    /Helvetica findfont 10 scalefont setfont
    100 100 translate
    /en   { gsave 0 0 moveto 1 10 string cvs show grestore } def
    /to   { gsave 0 0 moveto 2 10 string cvs show grestore } def
    /tre  { gsave 0 0 moveto 3 10 string cvs show grestore } def
    /fire { gsave 0 0 moveto 4 10 string cvs show grestore } def

%% method one
    [en to tre fire]{ 0 50 translate exec} forall showpage

    100 100 translate
%% method two 
    [1 2 3 4]{ 0 50 translate 0 0 moveto 10 string cvs show} forall showpage

I would expect "method one" and "method two" to be equivalent. But they are
not, but why ?
(method one prints all characters on top of each other,
 method two prints all characters one above the other:
   4
   3
   2
   1 )
In the PostScript book (Adobe on Addison-Wesley) the "forall" operator
is not (as I understand it) documented to save something.

Hope someone can enlighten me on this.
