void = List_LoadFromFile(sListVarName, sFullPathFilename, bCreateIfNeeded)

 

This macro function is used to read the contents of a list from a file on disk at sFullPathFilename.

 

➢All existing entries of the list sListVarName will be cleared and replaced by the contents of the file sFullPathFilename.

 

The macro code below loads the contents of a text file, processes each entry of the list, and then saves it back.

// load the list of country names override
List_LoadFromFile(sListCountryNames, sFullPathOfTextFile, true)
for nItem = 1 to List_Count(sListCountryNames) step 1
   // make some changes to some or all of the entries
   // ...
endfor
// save it back to file
List_SaveToFile(sListCountryNames, sFullPathOfTextFile)

When using lists, don't forget to always use the function List_Create to create your list at the top of the macro, and then the function List_Destroy to destroy it at the end of the macro.
