how to use global variable

[buffalokml]

Hi,

I've problem on using global variable. Maybe I did not use it correctly. Please help me to correct it.

From testcase.script.

function A

set myglobal = myvar1
....

return myvar1
end function A

function B
set myglobal = myvar2
.......

return myvar2
end functionB
=========================
From CommonShare.script

global myglobal

function mycom
put myglobal into runtimevar

open file and write runtimevar with new line.
.....
end mycom

I got error message: "unable to set global variable".

Thanks,

Best Regards,

Global variables can be confusing sometimes. The most important thing to keep in mind is that each script, or handler within a script, is independent in SenseTalk, and must declare any global variables that are used.

There are two ways to indicate that a variable is a global: either declare it on a global declaration line (a line beginning with the word "global" followed by a comma-separated list of variable names); or use the word "global" before the variable name in each place where it is used in the script.

Here is a tiny example script that illustrates their use. You should be able to create a new script, copy this code into it, and then run it:

Hi,

I am new to egg Plant, the code you have above does not show my problem.

I have 2 scripts 1 declaring 2 global lists and the other trying to use the lists and it does not work.

File 1 Named File_1 looks like this:

Hello Brick,

Yes, you can use global variables in any script. The trick is that you need to declare them as global in each script or handler where they are used. It looks like you're thinking that the "start using" command will do that for you, but "start using" only makes handlers from the other script callable.

To do what you want, just add this line at the start of your File_2.script:

Thanks Doug,

That works OK.
I was thinking the "start using" would do what I wanted.
