I am trying to write a Postscript file with a procedure defined in one page and invoked on both that page and subsequent pages. I know that defining the procedure in the prologue like this: /pr1 { % include procedure here } def %%EndProlog %%Page:? ? % do some postscript stuff % invoke the procedure pr1 gsave showpage grestore % go to a new page %%Page:? ? % do some other postscript stuff % invoke the procedure pr1 gsave showpage grestore % go to a new page %%Page:? ? works fine. The commands in the procedure pr1 are executed on both pages. I need, however, the following sequence to work: %%EndProlog %%Page:? ? % do some postscript stuff /pr1 { % include procedure here } def % invoke the procedure pr1 gsave showpage grestore % go to a new page %%Page:? ? % do some other postscript stuff % invoke the procedure pr1 gsave showpage grestore % go to a new page %%Page:? ? In this case, the commands in pr1 are executed on the first page, but not on the second. The Adobe Postscript manuals are not very illuminating as to what happens when you go to a new page. The save/restore commands looked promising but I couldn't figure out if they are what I need, and how to use them in this case. Since I've only tried this on a postscript viewer on my Iris 4d workstation, I am willing to accept the reponse that this should work- in which case the fault might be with the Iris. Any suggestions would be appreciated. If you e-mail to me at joe@etac632.gsfc.nasa.gov, I will summarize the responses. Thanks. Joe Fulson-Woytek
