When I try to open a text file larger than 600 MB with the function "FileReadEx" an error is thrown by the function.
However, if I open a file of about 300 MB this works without problems. Is their any sizelimit of the "FileReadEx" function?

My call is as follows:

blob lb_blob
longlong li_fnum, li_bytes

li_fnum = FileOpen("C:\temp\test.txt", StreamMode!)
li_bytes = FileReadEx(li_fnum, lb_blob)
FileClose(li_fnum)
 
The error message is as follows:
 
Bad runtime function reference at line 142 in function w_....
 
Info:
The development system has about 16GB of RAM.

The return value from FileReadEx is a long.
