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:

cMyStr=FGets(hFile,32767)
... Basically the equivalent functionality of FileToStr before it came along.

That apparently will now be broken. From the SP4 info:

FGETS function update

A minor behavior change was necessary for the FGETS() function related to Knowledge Base article.

The optional nBytes parameter now has a maximum value of 8192. By definition, FGETS() only returns bytes up to a carriage return if one is encountered before the parameter value is reached.
