175 +You can generate variables with text content. For this purpose, the variable type "**Text**" is available to you.

178 +
179 +To alter the value for the text variable, different options are available, which will be explained in the following sections.

206 +== Random selection ==
207 +
208 +Define a value list from which a value is randomly selected. The alternative values are separated by a line break, comma, or semicolon.
209 +
210 +If the selection value contains a comma, a backslash needs to be inserted before the comma. //(Example: "The condition\, which ...")//
211 +
212 +**Possible entries are for example:**
213 +
214 +* //Random selection: Car; motorcycle; bicycle: //One of the specified values will be randomly selected, for example "bicycle".
215 +
216 +=== Example "digging a hole" ===
217 +
218 +|(((
219 +[[image:attach:image2017-3-23 8:32:30.png]]
220 +)))|(((
221 +In the example, the text variable {PEOPLE} will be randomly initialised with one of the following values: "men", "women", or "children".
222 +)))
223 +|(((
224 +[[image:attach:image2017-3-23 8:36:15.png]]
225 +)))|(((
226 +To insert the variable into the task text, you need to type the variable name {PEOPLE}. In the example, the variable is included in a task of the type [[calculation (cloze)>>url:https://www.bps-system.de/help/display/ONYXintern/.Berechnungsaufgabe+v1.11||shape="rect"]].
227 +)))
228 +|(((
229 +[[image:attach:image2017-3-23 8:38:49.png]]
230 +)))|(((
231 +One of the defined values will then be randomly chosen for each participant and each test attempt. In the example, the value "women" was inserted.
232 +)))
233 +
234 +== Direct value assignment ==
235 +
236 +You can directly assign a value to all types of variables in order to initialise them. Later on, the value can be changed depending on other variables (cf. conditions).
237 +
238 +**Possible entries are for example:**
239 +
240 +* //Value: Hans: //The variable is assigned the value "Hans".
241 +* //Value: The function increases linearly: //The variable is assigned the value "the function increases linearly".
242 +
243 +== Calculation (MAXIMA) ==
244 +
245 +[[MAXIMA>>url:http://maxima.sourceforge.net/||shape="rect"]] allows for the work with strings and formulas. You can calculate variable values on the basis of other variables. Indicate your calculation rule in MAXIMA notation.
246 +
247 +**Possible entries are for example:**
248 +
249 +* //Calculation (MAXIMA): string({a}*x+5): //A simple function equation is calculated including the variable value {a}. Plase note that the variable {a} must have been previously defined.
250 +* //Calculation (MAXIMA): string(integrate({function},x,0,1)): //MAXIMA enables complex mathematical calculations. The derivative of a sample function (e.g. 5*x+5) could result in the value "15/2".
251 +* //Calculation (MAXIMA): tex1(matrix([{a1},{a2}],[{b1},{b2}])): //MAXIMA also facilitates the return of latex content.
