When I rang the company, the sales rep - who seemed to know Postscript quite well - said that he had been using it for some months. Re the showpage hidden ops. Presumably Adobe will publish them when they release full font details. Would anyone from Adobe like to comment? One option to find these special "unlisted" instructions is to dump the ROM contents using the PEEK operator posted a couple on months ago. If you look around, you can see the table containing all of the commands. Most of these are listed, but there are some very interesting others. When I tried some of these, I found that I was locked out (some cursing in the general direction of Adobe Corp. ensued...), but some others worked. Unfortunately I have neither the time nor the desire to chase this further. You will also find a ML montior at the start of the ROMs. It would be nice if somebody could figure out hot to get into it.
