Variables of several kinds, and graphics, may be embedded in a
message. Specifics and limitations of each type are given in Chapter
4; see page references in each section below.

When the insertion pointer is in the Message Edit box, open the
Format menu or click the Embedded Variables tool to display a list
of the types of variables, graphics and ASCII Control Characters.

This table represents the available Embedded Variables and

Placeholders

The number of symbols in the placeholder for a variable represents
the field width specified in its dialog.

Placeholders for all the variables in this table are displayed in the
Message Edit box in a different color from the rest of the text. You
can change this color using the Preferences dialog. See Page 7–15.

A placeholder may be removed using the Backspace key or the Cut
tool or command. It can be pasted only when the entire message is
copied and pasted as described on Page 7–8.
