DOS PRO - The fastest procedure, the disk: read / write sectors without monitoring and controlling errors reading sectors monitoring of the serviceability of reading, reading / writing sectors with the control interrupts the ignition / quenching lamp drive spinning and braking disc, reset VG13, positioned at 0 track, protection from Magic Button, blanking lamp drive, check what the current, control the availability of the disk in the drive.

Hello!
FAST M UP!!!
I, FASTER / TNL present to your attention the fastest
procedures for working with the disc today! Very
possible that this is not the limit! Therefore, if anyone
write faster any of the procedures, even necessarily
contact me! Procedure, I did not specifically comment on (and
everything is clear:) only where deemed necessary. I hope they
Will be useful (and not only once!) In your programs, especially
that they are fast and work well in TURBO mode (koim property
have not all procedures!). If you have any
questions, call! I'm a sociable and fun with
You communicate on any topic! ;)
So magnificent 15-scale ... ;)

(!) When writing procedures, the highest priority was speed,
and not volume!
When operating procedures are used only registers one at
Boron (in this case, the principal!): A, HL, IX, IY, BC,
DE.
Stack "strains" only to relieve himself!
Before calling the procedure (except the one that works
IM 2), we should prohibit the interruption (which, in
principle, not
It is a rule)!
(!) Before you will be presented to the procedure, I want to say
this:
1. When referring to TR-DOS ROM is used entry point:
# 3D30! This is not a rule ... (They say there are
components that are
not digested with this appointment! True to me like never
met!)
2. In reading # 1F algorithm is used (CooL!), proposed
LIMITED ANDREW MOA! I have met also with a vari
atsiey this algorithm (by Ivan Roshchin!). Well what can I
ska show?? Throughout my practice, when using the
algorithm by
MOA, I do not ever face a situation when the AL
Algorithm not working correctly! So there!
(!) PROtsedury run on all versions of TR-DOS (5.03 and above,
under the condition that they not made any "predatory"
changes)!
