@ SendCalc
var[,port]
Sends contents of
var
from a TI-89 Titanium to another
TI-89 Titanium.
If the port is not specified, or
port = 0
is specified, the
TI-89 Titanium sends data using the USB port if
connected, if not, it will send using the I/O port.
If
port = 1
, the TI-89 Titanium sends data using the
USB port only.
If
port = 2
, the TI-89 Titanium sends data using the I/O
port only.
SendChat CATALOG
SendChat
var
A general alternative to
SendCalc
, this is useful if
the receiving unit is a TI
-
92 (or for a generic "chat"
program that allows either a TI
-
92, Voyage™ 200,
or TI
-
92 Plus to be used). Refer to
SendCalc
for
more information.
SendChat
sends a variable only if that variable is
compatible with the TI
-
92, which is typically true in
"chat" programs. However,
SendChat
will not send
an archived variable, a TI
-
89 graph data base, etc.

Increments
var
from
low
through
high
by an
increment of
step
, evaluates
expression
, and returns
the results as a list. The original contents of
var
are
still there after
seq()
is completed.
var
cannot be a system variable.
