Remarks

Changing language and help file

In the WINDEV help editor, the name of help file can be built from a numeric identifier corresponding to Nation.
In this case, to start the help file corresponding to the current language, all you have to do is use the following code:
// Start the help in CHM format
WHelp("MyFile" + NumToString(Nation(), "03d") + ".chm")
