Setting a variable from the output of a shell script

I would like to use the output of the shell script "pwd" to populate a variable that I will then use to concatenate the argument to another shell script.
Below is what I tried, but that didn't work.
Any help is greatly appreciated.
set currentDir to do shell script "pwd"
do shell script "open " & currentDir & "/somedir/somefile"

Does an applescript always run from "/" or from the directory in which the applescript file is run?
From: http://developer.apple.com/technotes/tn2002/tn2065.html :
Q: What’s the default working directory for do shell script commands?
A: do shell script inherits the working directory of its parent process. For most applications, such as Script Editor, this is /. For osascript, it’s the working directory of the shell when you launched osascript. You should not rely on the default working directory being anything in particular. If you need the working directory to be someplace specific, set it to that yourself.

How do I set a variable on the main timeline from within a symbol?

Just getting started with Animate and coming to it from Flash, as may be apparent from my question. How do you set a variable to the main timeline from within a symbol?
I have 24 pairs of clickable elements, each in their own symbols, and all 24 of those symbols sit inside another symbol. I want all 24 to be able to set the same global variable when clicked. I can't find that this question is addressed anywhere, which makes me think I may be stuck in a Flash mindset and approaching the task in the wrong way. (There are however MANY discussions of how to address objects at different levels in the hierarchy. That's well covered.)
Relatedly, how do you access a function on the main timeline from within a symbol?
Adobe should consider putting together a support page (or pages) just for folks migrating form Flash. In the materials I've encountered so far there seems to be a studied effort to refrain from mentioning Flash in any way. I imagine there are a lot of people out there like me who have a deep background in Flash coding, but are just getting started with Animate. We don't need help with most of the basic concepts, but we may still have some pretty basic questions about how to accomplish some things in Animate because our Flash knowledge is getting in the way.

Hi Bill,
There are plenty of threads on here about scope, but here's one way to create a global variable:
// code on Stage.compositionReady
sym.myGlobalVar = 1;
Then, anywhere in your project, you can check/set that var like so:
sym.getComposition().getStage().myGlobalVar = 2;
And here's one way to create a global function:
// code on Stage.compositionReady
sym.myGlobalFunction = function(){
console.log('myGlobalFunction');
Then, anywhere in your project, you can call that function like so:
sym.getComposition().getStage().myGlobalFunction();

Dynamically Setting a Variable from a Connection String that has been set by a Config File

Hi Guys
I'm setting up a Master / Slave (Parent / Child) dtsx environment but I'm unable to work out how to dynamically set a variable in the Master dtsx from a connection string that has had its value set by a config file. I'm sure it's possible.
Below is the what I'm hoping to achieve. I've set up everything apart from the highlighted section.
Any ideas?

First, what version of SQL Server are you using?
You could switch the problem around. You could set the value of a variable from the config file, then it is easy to use that variable as the connection string source for your connection manager. At the same time you can use a parent variable
configuration to map that variable to variables in your child package.

Hi, I have quick question about use of USEBEAN tag in SP2. When I specify a scope of SESSION for the java bean, it does not keep the values that I set for variable in the bean persistent.Thanks,Sonny

Make sure that your bean is implementing the serializable interface and that
you are accessing the bean from the session with the same name.

How to delete multiple variables from the variables list

Hello,
Iam using FrameMaker 9.0. Is there a way I can select multiple variables from the book and delete them together.
Thanks,
CP.

NO in FM9. Take SQUIDDS TOOLBOX the free tool: 'Formats'
'Formats' is a very helpful tool for 'deleting' paragraph formats, character formats, cross reference formats, table formats, color definitions and variables.
You can delete unused one or all formats of selected. For paragraph and character you can also decide to 'add new one in catalog'.

Work Around !
You can execute OS commands using Jython script. Probably you need to flush your enviornment variables value into a file using jython script and then read those value into ODI variable from the file.
BUt may I know why you want to read environment variable vaules in ODI, Dont you think this will make your application less portable

Hi,
There is a simple solution provided by SAP to trigger the BILLING DOCUMENTS for Deliveries
This is a standard process
Setup a Job in SM36 for the program SDBILLDL and it will pick all the delivery document which are open on that particular Billing date
and process the Billing documents
Alternatively you can also create the IDOC to trigger the BILLING DOCUMENTS
For which you need to setup the PARTNER PROFILES, MESSAGE TYPES, PORT, RFC DESTINATION, SEGMENT CREATION,
But i would suggest you to go with the standard program to create the Billing documents

HT3349 How do you select a sub-set of cells from the entire document so you can print only those specific cells?

How do you select a sub-set of cells from the entire document so you can print only those specific cells?

There is no analog to MS Excels print range. So the next best thing is to plan your data so that you don't need to use print range. The next best thing after that is to select the range of cells you want to print, then copy, the switch to the application Preview, and create a new document from the clipboard (select the menu item "File > New from Clibboard") then select all, copy then paste to the destination (maybe an email) .
You can also paste that portion of the table into another table (or a new table) by pasting values only

I'm trying to connect a subVI with my VI, they both share common variables and the subVI is not reading one of the variables from the main VI...

I can't figure out why the subVI will not read this one particular variable from the main VI. How can I figure out how to make sure these two VI's are communicating properly?

Yes, please post example.
We could probably give you an answer rather quickly if you did.
