Read Command with Offset specified

[Gregory Lypny]

Hi everyone,

	I'm working on a utility that filters data in text files of more 
than 100 MB.  I want to read chunks of text from certain points in the 
file without running out of memory, so I was wondering whether using the 
Read-from-file-XXX-at-offset form of the Read command would actually 
read from the offset without loading all data before the read into 
memory.  If so, then it should be pretty easy to index key words in a 
first pass of the file before embarking on more intensive searches.
