Summary:
If you use the Cicode function FileOpen(Name, Mode) with the Mode option "a", then the Help states that if the file does not exist it will be created. However, if a folder, for example "Data" is given in the path name of the "Name" parameter as shown below, and the folder does not exist, then the function will return -1 as if it cannot open the file.

File=FileOpen("C:\Data\Report.Txt","a"); 
 

Solution:
Make sure that you create all the directories first that are in the path name that you have given in the "Name" parameter before using the Cicode function FileOpen(Name, Mode).
