I am having trouble understanding the syntax for oop. Here are some questions.
The source code below is from the help file.
FileS is File
FileD is file
ch1,ch2 are strings
//calling the file selection method
FileS :FileSelection()
FileD :FileSelection()

Question: Is the space suppose to be after the S in FileS???
//calling the method that checks the available space
If FileS:RemainingSpace(FileD :Directory) then
ch1= FileS:Directory+"\"+FileS :Name+"."+FileS :Extension
----------^---------------------^
-----No space here???------Space here???
What is going on.
ch1= FileD:Directory+"\"+FileD :Name+"."+FileD :Extension
fFileCopy(ch1,ch2)
else
Error("Insufficient space")
End
They also use :: when they create the method. Is this the only time you would use :: ?
What happen to FileS..Name syntax??
Any and all help is greatfully accepted. Hints and tips also.
Thanks

Forget the spaces. There are no spaces between the object and the method.
The difference between files..name and files:name is that in the first situation "name" is a property of "files", in the second situation "name" is a method (procedure) or a variable of the object "files".

Hi John,
:: will b e used if you have to use types or constant declared for a class. A :: is also for global method of a class.
Eg.
constant
cConst = 1
end
clMyClass is class
end
procdure method1(param1 is int, param2 is int = clMyClass::cConst)
