INTRODUCTION
The 4010A06
PLOT 10 Graphics Tablet Utility Routines provide
an easy
way of
using
the
4953 and 4954 Graphics Tablet
in conjunction with
a 4010—Series
Computer
Display
Terminal
and
a
host computer. The software
support
consists of six
FORTRAN
IV
sub-
routines which
are
designed
to
be
used with the Terminal Control System (TCS).
INSTALLATION PROCEDURE
1.
If
you
have Release
3.0 (or above) of
TCS load and compile the Graphics Tablet
Utility Routines (GTUR). Routines necessary
to
run
the
GTUR are TlNSTR, TOUTST
and
LE
FTlO.
If
your
TCS
package does
not
include these routines (part of
Release
3.0
and later) follow step
2.
2. If
you do
not
have TCS
(or
have
a
version lower than
Release
3.0) write the three
routines
as
shown below.
TOUTST
TOUTST
outputs
ADE* characters, including control characters,
in
an array.
Calling sequence:
CALL
TOUTST
(NCHAR, IAR RAY)
Parameters entered:
NCHAR
number of characters
in
array
to
be
output
IAR RAY
array containing
ADE characters to
be output
TlNSTR
TlNSTR accepts input characters and stores them
in a
buffer (IBUFF). The length of this
buffer
is
limited only by the maximum length of the computer system input buffer. The
input is'delimited by
a
carriage return (CR),
and it
is
not
necessary
that
control characters
be input. The subroutine must keep count of the number of characters
(NUM) in IBUFF,
not including trailing blanks. New
characters should
be
input only
if NUM=0, and the
output
buffer should
be dumped before
the
next request for input.
’ADE (ASCII Decimal Equivalent) code
is
the
integer
representation of the ASCII character
set. The
ADE characters are
the
numbers from 0 to 127. For example,
48
represents 0,
65 “A", 90
“2",
etc.
