It's because I'm not reading the file with RunRev, it's coming in via  
an external I've written to get around the >2GB File Limit problem in  
RunRev.

So, how can I get the *Real* Value of cr??

In the real code, I have a ReadUntil() function, this takes a  
character parameter for the "until" character. The function is  
defined like so:

function ReadUntil theFileForkRef,theUntilChar, at theDataBuffer

and I call it like so:

put ReadUntil(myFileForkRef,cr,myDataBuffer) into myOSStatus

Thanks a lot
All the Best
