<strong>Global</strong> <strong>Variables</strong> <strong>in</strong> <strong>AppleScript</strong><br />
In <strong>AppleScript</strong>, global variables allow you to def<strong>in</strong>e whi<strong>ch</strong> terms<br />
should be shared throughout the entire script. So if you set a global<br />
variable you can then access that variable anywhere <strong>in</strong> the script.<br />
Keep <strong>in</strong> m<strong>in</strong>d though that, unlike properties, you do not def<strong>in</strong>e a<br />
global variable when you create it:<br />
Open <strong>in</strong> <strong>AppleScript</strong> Editor<br />
global multiply_factor<br />
on run<br />
--Def<strong>in</strong>e Multiply_Factor<br />
set multiply_factor to 64<br />
--Use it <strong>in</strong> the math_problem subrout<strong>in</strong>e<br />
set the_answer to math_problem(16, 32)<br />
return the_answer<br />
end run<br />
--This subrout<strong>in</strong>e uses the multiply_factor variable even though<br />
we didn't pass it the multiply_factor variable dur<strong>in</strong>g the run<br />
statement.<br />
on math_problem(x, y)<br />
set new_x to x * multiply_factor<br />
set new_y to y * multiply_factor<br />
set f<strong>in</strong>al_result to new_x + new_y<br />
return f<strong>in</strong>al_result<br />
end math_problem<br />
