SendCalc var
Sends variable var to the link port, where
another unit linked to that port can receive
the variable value. The receiving unit must be
on the Home screen or must execute
GetCalc
from a program.
If you send from a TI -89 or TI-92 Plus to a
TI -92, an error occurs if the TI-92 executes
GetCalc from a program. In this case, the
sending unit must use SendChat instead.

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 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.

seq () MATH/List menu
seq( expression , var , low , high [, step ]) ⇒ list
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.
The default value for step = 1.
