@FILEREAD

@FILEREAD[n [,length]]: Reads data from the file whose handle is n. 
 Returns "**EOF**" if you attempt to read past the end of the file.  If 
length is not specified @FILEREAD will read until the next CR or LF (end 
of line) character.  If length is specified, @FILEREAD will read length 
bytes regardless of any end of line characters. 

If you plan to read text a line at a time, without using length, you 
should open the file in text mode.  If you plan to read binary data using 
length, you should open the file in binary mode.  See @FILEOPEN for 
details on opening the file in the proper mode. 

Be sure to read the cautionary note about file functions under Variable 
Functions.
