Level 1 compatibility operators

This page applies to Harlequin v13.1r0 and later; both Harlequin Core and Harlequin MultiRIP.

Level 1 implementations of the PostScript language, including the Level 1 version of the RIP, contained a variety of operators, mostly in statusdict, for controlling the raster and similar purposes. These were never published in the first edition of the PostScript Language Reference Manual [RB], but appeared in product-specific documentation, for example [EMERALD].

The Level 2 RIP implements these operators as procedures, which mostly make the equivalent calls to setpagedevice. They are provided for compatibility with older versions, and their use is not encouraged. Many of the compatibility operators are concerned with paper sizes in one way or another.
