!set embraced_randitem=<p>\

This field accepts the randomization by nestable curly embraces:\

if you put several words (or groups of words), separated by commas,\

within a pair of embraces, one of the words will be randomly drawn\

at the time when the text is presented to students. This will add\

randomness to your text.</p><p>\

For example, if you enter the text</p><p>\

<span class="tt">I will go to {Paris, New York, London}\

{tomorrow, the next week}</span>,\

the result will be one of the following sentences, at random:</p>\

<pre>\

I will go to Paris tomorrow\

I will go to New York tomorrow\

I will go to London tomorrow\

I will go to Paris the next week\

I will go to New York the next week\

I will go to London the next week\

</pre><p>\

If you wish to enter mathematical formulas, it is advisable to\

 disable this possibility by putting the switch\

 <span class="wims_code_words">Embraced random items</span>\

 on <span class="tt">$wims_name_no</span>.</p>

!set name_random=Some examples of random generation of parameter:<ul>\

 <li>For an integer between 10 and 100 (inclusive):\

     <span class="tt wims_code_words">randint(10..100)</span>\

 <li>For an integer multiple of 10 between 10 and 1000 (inclusive):\

    <span class="tt wims_code_words">randint(1..100)*10</span>\

 <li>For a decimal number between 0 and 2:\

    <span class="tt wims_code_words">random(0..2)</span>\

 </li><li>For a random item within a list:\

    <span class="tt wims_code_words">randitem(a,b,c,10,100,word,a phrase)</span>\

 </ul>

!set name_detail_parm=More details on the computation of parameters.

!set image_help=<h4>Inserting images</h4>\

To insert images in your exercise, you must first load the images\

 in the exercise module of your class and secondly put the html code that displays the image.\

The insertion code is\

<pre>&lt;img src="\imagedir/nom_image"/></pre>,\

where <span class="tt">nom_image</span> is the name of the image (including the <span class="tt">.jpg</span>, <span class="tt">.png</span>,\

... extension) and <span class="tt wims_code_variable">\imagedir</span> represents the directory where the image is located.\

You can put it in most of the texts of the prepared models (including in the instructions).\

You can start your exercise even if the images are not uploaded yet.\

Once the exercise is in the classroom, follow the link\

<span class="tt">Upload a file</span> in the exercise</tt> or <span class="tt">$wims_name_downloadbinary</span>\

and upload all the images you need. Test, then adjust the image sizes.\

It is recommended that you do not take images that are too large,\

 because they take longer to load while performing the exercise\

 and reduce them before putting them in the classroom module.\

!set math_help= <h4>Inserting mathematical formulas</h4>\

To enter mathematical formulas, enclose the tex code by \

<span class="tt wims_code_variable">\(</span>\

and\

<span class="tt wims_code_variable">\)</span>.\

For example,\

<pre>\( x^2+\frac{3}{2} \)</pre>

!set oef_help= <div class="wims_smallremark"><h4>For the most advanced</h4>\

it is possible in the definition of the parameters\

 to use most of the functions of the OEF exercises.\

</div>

!set credits_help=<h4>References</h4>\

You may use the field <span class="tt wims_code_words">$wims_name_credits</span> to give\

short references, for example for the images inserted in the exercise.
