@ 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

high
 by an 
increment of 
step
, evaluates 
expression

returns the results as a list. The original contents 
of 
var
 are still there after seq() is completed. 
var
 cannot be a system variable. 
The default value for 
step = 
1.

Sets the clock to the date given in the argument

{
yearold,monthold,dayold
} format. The returned date 
is the previous clock value. 
Enter the year as a four-digit integer. The month 
and day can be either one- or two-digit integers.
