Calling a Program from Another Program
On the TI
-
86, any stored program can be called from another program as a subroutine. In
the program editor, enter the subroutine program name on a command line by itself.
♦
Press
8
to display the
PRGM NAMES
menu, and then select the program name.
♦
Use ALPHA keys and alpha keys to enter the program name’s individual characters.
When the program name is encountered as the calling program runs, the next command
executed is the first command in the subroutine. It returns to the next command in the
calling program when it encounters
Return
(or implied
Return
) at the end of a subroutine.
