I've written a screen dump routine (in Turbo Pascal), based on the screen
dump approach described in the green postscript recipes (I don't have teh
exact details of the book in front of me).  It works fine, but if I have
several screen dumps in one file they come out alternately OK and then
white on black!!  I don't really know anything about PostScript, but I gues
I have got to put a specific command at the end of printing one screen to 
restore to black on white.  The final commands, after the screen image, are

  grestore
  showpage

I thought the grestore would fix it up, but obviously not.

If anyone can follow these garbled instructions and can help me out, I'd
be very grateful.

Thanks, Ian Johnson
