Thanks, You can't normally 'navigate' around a PostScript file, because its not designed that way, there is no way to tell where one page starts and another ends (without interpreting the whole document). In addition its perfectly possible to have a PostScript program which only works if you execute the pages in the correct order, because later pages rely on definitions from earlier pages, such as fonts. In order to permit this navigation the file needs to be DSC (Document Structuring Convention) compliant. That is, it needs to have certain comments present to enable the application to know how many pages are in the program, and where the beginning of each one is, and also needs to be constructed so that each page is atomic (or at least relies only upon setup done in a defined, commented, section) Ideally it also needs to know the size of each page. Your example, while perfectly sound PostScript, doesn't conform to DSC, and this is almost certainly why it doesn't work as you exepct. I don't know exactly what it is that the application in question needs to allow this to happen, but I would imagine at least a '%%Pages: 2'. Your file also *must* declare itself as being DSC-compliant, this is done by altering the conventional %!PS comment to one of the form %!PS- Adobe-x.y where x and y are the major and minor revision numbers of the DSC specification which the document complies with. Tech Note 5001 (available somewhere on the Adobe web site) documents DSC. Ken
