-------
<br>
The MIDAS logger ([[mlogger]]) is able to record information in an ASCII file.
 
Under two dedicated subdirectories
[[Keys in the ODB /Logger/Runlog/SQL subtree #/Logger/Runlog/SQL/Links BOR | Links BOR ]] and
[[Keys in the ODB /Logger/Runlog/ASCII subtree #/Logger/Runlog/ASCII/Links EOR | Links EOR ]],
predefined links exist which will be used at begin-of-run (BOR) and end-of-run (EOR) respectively for storing parameter values into an ASCII file. These elements are [[ODB Page#symbolic link|ODB links]] allowing the user to extend the list with any parameter in the ODB database.
 
The following example shows a <span style="color: purple;">''/Logger/Runlog/ASCII''</span> tree as created by [[mlogger]]. See [[keys in the ODB /Logger/Runlog/ASCII subtree |ODB /Logger/Runlog/ASCII subtree]] for an explanation of the meaning of each key.
