Abstract: FAST is a collection of file open, read, write and close
subroutines that may be used to perform block
(unbuffered) I/O to a random access device under RSX
FILES-11. This is desirable because unbuffered I/O will
permit the fastest possible throughput rates to disk,
and this is valuable for real-time (or time sensitive)
applications. The subroutines allow for sequential and
direct access operations. Support is provided for fixed
record length data transfers only; i.e. after the record
length is specified during a file open procedure, all
I/O will attempt to transfer that same amount of data.
All software is written in MACRO-11 and a subroutine
user's manual is provided on the media.
 
Restrictions: This software only works with fixed record length I/O.
