In a system without pointers, you might have to do something like this to work with a(n external) file: | |||
int handle = FileOpen ("temp.tmp", FILE_WRITE); | |||
if (handle == 0) Display("Error opening file."); | |||
else { | |||
FileWrite (handle, "test string"); | |||
FileClose (handle); | |||
} | |||
This is difficult to work with because you have to create a new integer handle the file, use it while working with the file, and then make sure to close the file using it's handle. | |||
In a system with pointers, you can do this instead: | |||
File *output = File.Open("temp.tmp", eFileWrite); | |||
if (output == null) | |||
Display("Error opening file."); | |||
else { | |||
output.WriteString("test string"); | |||
output.Close(); | |||
} | |||
You still have to create a variable (or rather a pointer) to handle the file, but it becomes much more clear what it is for (as opposed to integers which are likely much more common in your scripts). | |||
