Mark,
This would have broken with SP3, the change to a maximum of 8192 was implemented then. Check out MS KB article Q221747.

BTW, FGets always stopped at a carriage return so I'm not sure what the problem is. FRead would have been my choice in this scenario.

>Take a look at the SP4 update notes for VFP. How many people have legacy VFP code out there, before the FileToStr function came along, that _knows_ it's going to reading an entire textblob file of some arbitrary length less than 32K characters and is simply coded as:
