Details:

Condition: When open too many files for reading inside function 
Behavior: environment does not find and recognize basic commands like save(),
plot() after function finishes

It was tested at 1264 files opened for reading.
See attached files.

4 files attached:
ren_read1.m - procedure executed;

function dirstruct40_ fills cell array with filenames to be opened (before
running it should be edited to look for existing files on certain machine);

function readList1_ represent cycle to open and read files;

function readPos2_ opening and parsing file (needs to be edited to be able
open existing files on certain machine, parsing can be skipped or modified)

If comment line 23 (fclose(fid);) in this function readPos2_   then
environment became unstable and unresponsive after function completed.

No error or warning is displayed showing that opened files were not closed.
Actually it make sense that all these files which were opened to be closed
automatically when function finishes, or otherwise show error if fail to do
so.
