[Gambas-bugtracker] Bug #1696: Write of a string[] to a MEMORY FILE only save or reads first element, lof() always returns zero on memory file

http://gambaswiki.org/bugtracker/edit?object=BUG.1696&from=L21haW4-

Brian G reported a new bug.

Summary
-------

Write of a string[] to a MEMORY FILE  only save or reads first element, lof() always returns zero on memory file

Type             : Bug
Priority         : High
Gambas version   : 3.14
Product          : GUI components


Description
-----------

Two issues around memory files

A write of a string array only seems to save the first element, the same number of elements are returned but all elements after the first are empty strings

LOF() on a memory file always returns 0 although Seek() returns the next position working.

I have included a test file, in development.

If I can help fix the problem?
