Error from large files?

I am having trouble reading/inputting from some large files. I get this message: "not enough values for attribute list in SET/GET (-11273)". Smaller files read just fine. A program written in C will access the large files, so they, at least, are OK. I would rather use true basic! These are large text files (>2.8 G) and I cannot access but either ORG TEXT or ORG BYTE. Has anyone else had this problem?
