formulae. It is recommend to use it when the focus is on appearance.
Data is entered on the left-hand side in natural mathematical

The user can choose between various display options:
- Standard: The formula is displayed with the aid of variables.
- With numerical values: Either the variables and the numerical values or just the numerical values are displayed. If both are displayed, it is possible to determine whether the formula is displayed on one line or two. The latter is recommended or may even be necessary for longer

Variables and numerical values can be entered directly via the keyboard.
Entry of a term is concluded with ENTER or with an arithmetic operator. The "+

In addition, the key combinations CTRL+D
for superscripts and CTRL+T
for the square root function simplify the input.
: After completing the entry of a term, the cursor keys can be used to navigate in the formula editor.
complex formulae are created trouble-free with the buttons on the
right. For very complex formulae, it is recommended to set up
the basic structure first.
Begin with the root function sign,
for example, and the essential fraction strokes. Then fill in the
Greek characters and trigonometric functions are inserted using the lower selection buttons. Incorrect
entries can be cancelled using the arrow buttons.
All defined variables can be adopted automatically using the

calls up the mask for modifying the variables. The height, width and baseline are shown in pixels. The
latter defines the vertical position in the text.
: In the case of normal font sizes (9 to 12) the baseline interval is 6 pixels. The height and width result from the
entered symbols. Guideline value for the height: 2 x font size + 6.

VCmaster's Variable List
provides effective assistance. It displays all
variables available for further calculation at the current text
passage. The variables can be selected and transferred into a new
formula. Indices are also taken into account and do not have to be
entered again. Brackets and arithmetic operators can be addressed
directly. Another option is to write parts of the formula in the text
and extend it by using the Variable List
(or vice versa).

The Variable List

Additionally the lower part displays the value of the variable. Has a
text been entered prior to the variable, it is also displayed. Therefore
the Variable List
is well-suited for checking values.

While entering data a list of variables can be called up. This list is placed at cursor position. Results are refined after entering the first letter(s).
Simplifying and accelerating the input of variables, as specific variable names are not always present. Fast input mode also prevents unnecessary typing errors and associated corrections. Navigation in the variable list is carried out via cursor.
Variables are selected using either the Enter key or the Space bar.
