yes. Hypertext. fork from inside Wave or from OS prompt.
The vast majority of the reference manual is there, and some of the users guide.
Version 4.2 (Jun/Jul 93) is supposed to have the ENTIRE manual set on line,

yes

As part of the SQL table functions, there's BUILD_TABLE, which builds a

TIFF, Sun Raster file, but no GIF

you can even use strings or Date/Time labels
