Examples

Math Random and SetRandomSeed Example

In this example, Math.SetRandomSeed is used to make sure the result is the same for every rendering. Then a mathimatical addition is assembled using the For macro together with Math.random. Finally, the expression is evaluated using String.Eval.

{math.setrandomseed(12345)} <se:for from="1" to="10" whitespace="remove" save="rnddata"> {sys.iif(this.index() GT this.getparameter(from), ' + ', rem='skip for first enty')} {math.random(1,100)} </se:for> Calculate: {buffer.get(rnddata)} Result: {string.eval($rnddata)}

<se:for from="1" to="10" whitespace="remove" save="rnddata">
    {sys.iif(this.index() GT this.getparameter(from), ' + ', rem='skip for first enty')}
    {math.random(1,100)}
</se:for>

Calculate: {buffer.get(rnddata)}
Result: {string.eval($rnddata)}

Random DataTable Example

This example generates a datatable with random data. The number of rows in the datatable can be controlled by setting the to-parameter of the For macro. The word count for the text field can be controlled by changing the value for the wrdcnt buffer.
