- The
**input of calculations appears directly in the text program**. It is sufficient to write a formula such as M = q * l^{2}/ 8 or τ =T_{eq }/ Wt in any empty line and to call up the "*Calculate Line"*function. - Unlike spreadsheet calculation programs,
**no cells**are required. - The calculation line can include a preceding text, as the equals sign or the colon character separates this from the formula. The unit of measurement can be specified directly after the formula and separated by a space character.
- The program interprets the calculation line completely automatically. Units of measurement, format and decimal places are queried if necessary (it is important to refer to Chapter 2.4 for further information). Dependent values are identified and calculated accordingly.

**(Important tip:**Please note that the documents transferred from other countries with country specific characters can be interpreted incorrectly if the country settings in windows-systems are different. This is especially encountered when the code page is different for e.g. east and west Europe.) - May only contain numerical values and alphabetical characters (including Greek characters and umlauts); the following special characters are allowed: full stop, comma, infinity, underscore and square brackets.
- Several characters are inadmissible including superscript characters, round brackets, semicolons and mathematical operators. The following variables cannot be interpreted mathematically: h
^{2}= ... ; b/2 = ... ; X(20) = ...

**Exception**: Expressions in square brackets will not be interpreted mathematically so that variables like M_{[G+Q]}are possible.
