ACKNOWLEDGEMENTS
This manual was largely compiled from material prepared
BY THE STAFF OF THE UNIVERSITY OF MICHIGAN COMPUTING CENTER.
Their documentation was invaluable and we are indebted to THEM FOR ALLOWING US TO USE IT. IN PARTICULAR, THE FOLLOWING WERE MOST USEFUL!

Introduction to MTS and the Computing Center (Flanigan) Computing Center News Items Computing Center Memos
The Computing Center wishes to personally acknowledge the ASSISTANCEOFMK i EALEXANDERAND DoN BoETTNER WHO HELPED USTO ESTABLISH MTS AT THE UNIVERSITY OF ALBERTA.
Acknowledgement should also be made to the Computing Centre, University of British Columbia, for information obtained from
SOME OF THEIR DOCUMENTATIONAND TO I.B.M., WHOSE MANUALS PRO VIDED CERTAIN SECTIONS FOR OUR MANUALS.
DISCLAIMER
This MTS manual is a combination of earlier manuals,
update notices, memos and limited experience with the system itself. Because of this, certain discrepancies are bound to occur and the Computing Center would appreciate being notified
of ail differences between what this manual says and what the sys tern actua]1y does .
This publication is intended to represent the current state-of-the-system. However, it should not be construed as an obligation to maintain the system as so stated. The MTS
system, like most good systems, is continually being improved. As a result, additions, extentions, changes and deletions will occur. Notice of such changes will be made and provision for a manual updating service has been planned.

Entering MTS Lines: Alphabetic (^Tha ra tej]^ in command
lines are always converted to upper case before the command line is analyzed; thus $SIGNON and $signon produce the same effect. Alphabetic characters in data
lines are automatically converted to upper-case. If this
automatic conversion is not desired, entry of lower-case characters can be accomplished using the device c o m m a n d , t h e $ S E T c o m m a n d , o r t h e @ L C m o d i fi e r . Four characters are assigned special control functions for

of device commands to set margins, tab-stops and perform a number of other functions. A device command consists of a
% sign in column 1 followed by a command identifier and an operand.
A device command must appear exactly as described in t h e c o m m a n d d e s c r i p t i o n s g i v e n b e l o w. L i n e t e r m i n a t i o n must occur immediately after the last character of the de
vice command. The addition of a trailing blank (or blanks) will cause the line to be transmitted In the normal fashion.
All input lines are monitored (after the usual editing for l i t e r a l n e x t , d e l e t e p r e v i o u s , d e l e t e l i n e a n d e n d o f fi l e
characters) so that any line which constitutes a valid device command is intercepted and acted upon rather than be ing transmitted as an ordinary input line. D e v i c e c o m m a n d s f a l l i n t o fi v e g r o u p s a s f o l l o w s : 1.

to the logical I/O unit will cause a read operation on the terminal, and conversely a write operation to a logical I/O unit assigned to *SINK» will cause a write operation on the t e r m i n a l .
The user can redefine ^SOURCE* and "SINK» by using the $SOURCE or $SINK commands, however it should be noted that an attention interrupt on the terminal will cause ^SOURCE* and
