Texas Instruments TI-84 PLUS - Graphing Calculator - Calling Other Programs as Subroutines

Chapter 16: Programming 293
GetCalc(variable[,portflag])
By default, the TI-84 Plus uses the USB port if it is connected. If the USB cable is not connected, it
uses the I/O port. If you want to specify either the USB or I/O port, use the following portflag
numbers:
portflag=0 use USB port if connected;
portflag=1 use USB port;
portflag=2 use I/O port
Note: GetCalc( does not work between TI.82 and TI-83 Plus or a TI.82 and TI-84 Plus calculators.
Get(, Send(
Get( gets data from the CBL 2™ or CBR™ and stores it to variable on the receiving TI-84 Plus.
variable can be a real number, list element, list name, matrix element, matrix name, string,
Y= variable, graph database, or picture.
Get(variable)
Note: If you transfer a program that references the Get( command to the TI-84 Plus from a TI.82,
the TI-84 Plus will interpret it as the
Get( described above. Use GetCalc( to get data from another
TI-84 Plus.
Send( sends the contents of variable to the CBL 2™ or CBR™. You cannot use it to send to another
TI-84 Plus.
variable can be a real number, list element, list name, matrix element, matrix name,
string, Y= variable, graph database, or picture.
variable can be a list of elements.
Send(variable)
Note: This program gets sound data and time in
seconds from CBL 2™.
Note: You can access Get(, Send(, and GetCalc( from the CATALOG to execute them from the
home screen (Chapter
15).
Calling Other Programs as Subroutines
Calling a Program from Another Program
On the TI-84 Plus, any stored program can be called from another program as a subroutine. Enter
the name of the program to use as a subroutine on a line by itself.
You can enter a program name on a command line in either of two ways.
• Press  | to display the
PRGM EXEC menu and select the name of the program prgmname
is pasted to the current cursor location on a command line.
