 to indicate the text alignment and tab stops for any given portion of the text. A typical editing session might have looked like this:

Text conformed to the preceding ruler (now offscreen). ----L----T-----------------------------T---------------------------------------------R---- Text conformed to the ruler shown just above L -> Left margin R -> Ragged-right margin T -> Left-aligned tab ---------L----------------------------->---------------------.-----------------------J---- > -> Right-aligned tab . -> Decimal-aligned tab J -> Justified right margin (not justified on screen, only on printout)

Aligned with the right tab Decimal-point aligned$5.99 1279.99

Using these various rulers, complex formatting could be achieved, even using a simple input device like a 24x80 character terminal. On ANSI terminals, character attributes such as bold and underline were shown on the screen. On the VT52 terminals (which could not display attributes), the operator could perform the same functions but only the printout would reveal the formatting.

As text was typed-in, the system automatically word-wrapped the text so that it conformed to the ruler currently in effect for that section of the document. Rulers could be added or modified and the text from that ruler forward to the next would automatically be adjusted to conform to the new ruler. Hyphenation could be semi-automatically performed (including "hidden" hyphens that would only be revealed if a line break exposed them).

Specialized editing functions were provided using the terminal keypad. A few functions could be commanded simply by pressing a keypad key, but a far wider range of functions could be commanded by prefixing them with the "Gold Key" (the PF1 key on the keypad, colored gold on systems equipped with the WPS-8 custom keycaps). This style of "gold key" editing also became endemic at Digital, later showing up in mainstream general-purpose text editor

WPS-8 normally ran from a single floppy diskette and user data could be stored on the system diskette or additional data-only diskettes. Up to four diskette drives were supported in a single system.

The system also supported the creation of data tables, the sorting of these data tables, arithmetic calculations using these data, and a mail-merge operation using these data and the arithmetic results. Through the extensive use of overlays
