To avoid facing too many errors at once, the general strategy is to make "one small change" at a time, do a run show-preview, and then save that tested version after a few good changes to have a stable version to restore, in case terrible errors occur after numerous later changes. Note: the saving of each working copy can be done to a set of offline text files, perhaps each with a specific version name (and internal comments), rather than saving each version into the Wikipedia module revisions.

== How to debug==

===Simple review===

To see the value of a variable in a single point of the module:

Line 58:

===Review of the flow and the variable values in several points===

The functions of the [[Module:SimpleDebug]] arecan be used for cases such as those mentioned above or for more complex cases:

* When a variablevariables or the returned value (or values) by a function are local.

* When a variable (or several ones) take the values (to see) in different points (even in required modules).

* To see if the flow of the program goes through a point (to which you will label).

* To limit the number of values returned from a loop or set conditions to enable the registration of values.
