In the PostScript Reference Manual, the cause of the error invalidrestore is said to be that the operand-, dict- or execstack contains composite objects whose value were created later than the saveobject that is being restored. Take a look at this example: %! 10 dict begin /saveob save def userdict /keepdict currentdict put end keepdict begin saveob restore (ok.\n) print This program produces an invalidrestore, atleast on the LW+ I used. If the line starting with end is removed, it works. But that line only pops the dict off the dictstack and pushes it back again! Is this a bug or am I thinking wrong? Thankful for any explanations, either here or to me or to f86.fredric-ihren@vera.nada.kth.se Johan Ihren Royal Institute of Technology, Stockholm, Sweden.
