   If I understand you correctly, you want to take PostScript code, 
tweak or edit it a little interactively while displaying it to make
sure it still works, and be able to send the edited PS file somewhere
when you're done. If so, yes, the NeXT is pretty ideal. One of the supplied
demos (named 'Yap') is basically an editor connected to a scrollable
window; press a button and the PS is reimaged in the window. You can
save, clip&paste, etc. as you could with any text editor. Or you could
edit with a different editor and use the PostScript previewer instead;
I'm not sure whether this would have any advantadges (I use Yap when
I'm drawing my own figures and diagrams, myself...)  
   Thing is, the PostScript interpreter (Display PS, but DPS is only
an extension to PS) is part of the OS, so it's trivial to write a 
PostScript previewer (Yap is a pretty short program...)
