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.
