Nope, not even close, there's no %%Pages: or %%Page: comments. His description of the first line is completely wrong, it's what DSC version it's complient with, not the PostScript level. The DSC %%LanguageLevel: comment is how a document identifies the minimum PostScript level it needs. -- -- Rod -- rodd(at)polylogics(dot)com
