Calling
Sequence:
CALL
TlNSTR
(LEN, IARRAY)
Parameters entered:
LEN
the number of characters requested
IARRAY
ADE
array into which the input characters are
placed
NOTE
If
LEN>NUM>0, /ARRA
Y
must be
padded
with
spaces.
if
LEN <NUM,
characters remaining in the
buffer
should be
retained
for the next
access
of
TINS TR,
and
NUM
should be updated
to
NUM
——
LEN.
LEFTIO
LEFTIO
returns
to number of characters left
in
the TINSTR buffer
(NUM
above).
Calling
Sequence:
CALL
LEFTIO
When
the above routines
are
written you should
be
able to
load,
compile, and
run
the
GTU
R.
3.
Subroutine
MULPNT
contains
a
comment line
which
allows
the
user
to
insert
a
sub-
routine BUFFUL for buffer overflow:
C
* lF(NGOT.GT.NWNT)
CALL
BUFFUL
By
replacing “C *” with
spaces
and writing BUFFU
L,
the user
may
create
a
routine
which will handle buffer overflow. The standard
GTU
R
package discards any input points
in
excess
of the
limits of the buffer. BUFFUL could
be used
to
call
a
terminal
bell
routine
to alert the user when the buffer overflows.
