On the TI-83, 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 (page 16.7). prgmname is
pasted to the current cursor location on a command line.
• Select prgm from the PRGM CTL menu, and then enter
the program name (page 16.15).
prgmname
When prgmname is encountered during execution, the next
command that the program executes is the first command
in the second program. It returns to the subsequent
command in the first program when it encounters either
Return or the implied Return at the end of the second
program.

label used with Goto and Lbl is local to the program where
it is located. label in one program is not recognized by
another program. You cannot use Goto to branch to a label
in another program.
Return exits a subroutine and returns to the calling
program, even if it is encountered within nested loops.
