>PS. You rarely need to resort to low level file I/O, using FOPEN(), to import a text file into a table. Low level File I/O is also probably the slowest way to process the file. On a PC with a lot of RAM, you may also find that your (millions) of records can be imported straight into a text variable using FILETOSTR() and then popped into an array using ALINES().

Ok, tried the above and I get an error saying my computer doesn't have enough memory to complete the operation. These are massive .txt files. Is there a way to just read one line or a chunk of lines at a time from them?

Thanks!
