	151	+== Random selection ==
	152	+
	153	+Define a value list from which a value is randomly selected. The alternative values are separated by a line break, comma, or semicolon.
	154	+
	155	+If the selection value contains a comma, a backslash needs to be inserted before the comma. //(Example: "The condition\, which ...")//
	156	+
	157	+**Possible entries are for example:**
	158	+
	159	+* //Random selection: Car; motorcycle; bicycle: //One of the specified values will be randomly selected, for example "bicycle".
	160	+
	161	+=== Example "digging a hole" ===

	163	+|(((
	164	+[[image:attach:image2017-3-23 8:32:30.png]]
	165	+)))|(((
	166	+In the example, the text variable {PEOPLE} will be randomly initialised with one of the following values: "men", "women", or "children".
	167	+)))
	168	+|(((
	169	+[[image:attach:image2017-3-23 8:36:15.png]]
	170	+)))|(((
	171	+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"]].
	172	+)))
	173	+|(((
	174	+[[image:attach:image2017-3-23 8:38:49.png]]
	175	+)))|(((
	176	+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.
	177	+)))
	178	+
	179	+== Direct value assignment ==
	180	+
	181	+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).
	182	+
	183	+**Possible entries are for example:**
	184	+
	185	+* //Value: Hans: //The variable is assigned the value "Hans".
	186	+* //Value: The function increases linearly: //The variable is assigned the value "the function increases linearly".
	187	+
	188	+== Calculation (MAXIMA) ==
	189	+
	190	+[[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.
	191	+
	192	+**Possible entries are for example:**
	193	+
	194	+* //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.
	195	+* //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".
	196	+* //Calculation (MAXIMA): tex1(matrix([{a1},{a2}],[{b1},{b2}])): //MAXIMA also facilitates the return of latex content.
