The purpose of a code unit is to be a single self contained unit of code (procedure, function or method) that does a SINGLE job and does it WELL.
If you make that code unit reliant on data inside another code unit, that self containment is violated. A dependency is created. One that a developer working on ProcA can break as this developer will be unaware that ProcB is dependant on data in ProcA. (this concept is also not supported in most programming languages)
This is why code units need to exchange data as parameters (or via properties in o-o languages).
Likewise is the idea of global variables not always that sound. Global variables need to be correctly identified and implemented. Assuming that global variables are truly needed, then there are two basic ways to address this.
Session based. I.e. global variable values that are only seen by code within the same session. This can be implemented as a PL/SQL package, as an Oracle Context (name-space), or as a temp table.
Database based. I.e. global variables that persist across all database sessions (and instances if RAC). This can be implemented as a standard database table (with a PL/SQL package interface that provides and sets values).

I have two separate itune accounts under two different email accounts and would like to combine them under one account. Is this possible and if so, how do I do it?

If you go to Settings > iTunes & AppStore , you can sign out from your account, and sign in with the one you've used to purchase apps.This will not remove any apps you already have on it.
Then you can go to AppStore and download apps you've purchased (either via "Purchased" button in "Updates", or simply search for them and download them.
That way you can have multiple accounts' apps on your iPad. When updating, you will be prompted for the credentials for account you've purchased given App with.

Is there a way to have two separate projects open in different windows?

On my old editing software, I could have two separate projects open at the same time. I could copy clips from Project A, click over to Project B, and paste the Project A clips to Project B. Is there a way to have two separate projects open with Premiere Elements, or will I have to just import and trim every clip within the same project?

Welcome to the forum.
Unfortunately, PrE will not allow two Projects to be open at the same time. It will also not allow multiple instances of PrE to be open.
The workaround, to accomplish what you describe, is to use a ClipBoard Extender, such as ClipMate, which will allow one to Copy a Timeline, or parts of it, from one Project, then Close that one, to Open another one, and Paste the material, that was Copied. Many users employee ClipMate, or similar, to Copy/Paste material from one Project, to another.
Good luck,
Hunt

I have two separate iTunes libraries on two separate Computers. I need to consolidate them so I can play them on a brand new computer. How do I do this so I can play them off an External Hard Drive on my brand new computer?

Why, if it told you you have insufficient space on your computer, would it suggest making more space available on your phone?
At a guess, you have insufficient space on your phone. Installing software will typically require more space than the final size of the software, perhaps even twice or three times as much, for the installation process. You can easily dump some videos or music temporarily, and then synch them back in afterwards.

Can I have two separate iTunes accounts on the same computer?

Can I have two separate iTunes accounts on the same computer? My wife's music is much different than mine. Can we have different iTunes libraries to work with on the same computer?

Yes. Launch iTunes with the Shift key held down as needed, or use separate Windows user accounts on the computer.

Can you have two separate iTunes files on one computer?

I gave my daughters each an old iPOD. One is 20 GB and the other is 60 GB. I take an iBOOK laptop with me when I visit so I can update them. In the past, they shared the 20 GB iPOD only. Now I have a problem as one iPOD can store a lot more than the other. Is there any way to have two separate iTUNES files on one iBOOK computer, one with the songs for the 20 GB iPOD, and the other for the 60 GB iPOD?

The problem with making separate accounts is that this is a laptop, so likely not a huge hard drive, and if the three iTunes libraries need to have a lot of the same music (because everyone or two or three like some of the same stuff) you end up with double or triplicate copies of the music on the hard drive eating up drive space. Since they don't use his laptop normally, creating more accounts (with all the associated files and drive space usage each account would eat up) it probably isn't worth it.
Instead, the best approach is like Chris said, to make playlists for the girls in the main library and then set up the various iPod to either sync everything (if big enough) or sync only specific playlists (if not big enough).
Alternatively, they can set their iPods to manual syncing and then when Dad is visiting they can hook up their iPods and "shop" the library and drag in whatever they want to add to the iPods and delete what they no longer want.

I appear to have two separate Apple IDs and have purchased music under both. Is there any way to consolidate the accounts into one?

I appear to have two separate Apple IDs and to have purchased music under both of them (one is my husband's email account, the other is mine). Is there a way to consolidate them, or is it possible to make the purchases made under two separte IDs downloadable on the same device(s)?

Not at this time. There is no way to merge two Apple IDs or be signed into the iTunes Store with more than one Apple ID at a time on an iOS device. However, you can USB sync the music to more than one device at a time, no problem. As long as all the music is on the same computer.

I have two separate iCloud accounts. How do I merge them?

I have two separate iCloud accounts, one at mac.com and one at me.com. But I only want to have one iCloud account. How do I merge the two into one keeping all the data in each?

If you have two accounts with separate iTunes Store purchases, only a senior Apple support tech can help you with that. It took several hours for mine, when a total stranger hijacked my email to use for their own (no, they could not access my account, but I was getting email from their connections. Like, D'Oh!) Going by what you're saying in your message, as long as your email ID has the same name preceding the @, all emails still go to you. I also have all three, but only use the first one.

Can I have two separate email addresses in my mail?

Hi,
Can I have two separate email addresses/users with my one email account without paying anything extra?
For instance: one email address with [email protected]
And another one at: [email protected]
And, if that's possible:
1. Does it mean paying extra because you are having two separate accounts?
2. Since it is on the same general account, do the emails and return emails show in the same location or do they show in a different place? For instance, if the 2nd user sends and email and someone returns it, will I as the first user name see both of those?
Thanks much,
Lee

You can have up to five additional addresses, but they are not separate accounts. They are called 'email aliases' and are simply extra addresses which feed into the main inbox (and please note that you cannot create any new @mac.com adresses, they will be @me.com). Please see here about aliases:
http://homepage.mac.com/rfwilmut/notes/mobileme.html#alias
It's actually a good idea to give everyone an alias address rather than the main one, since if it gets spammed you can easily change it, whereas as you can't change your main address without opening a new account.
If you need extra email accounts then you could go for a MobileMe Family Pack. Of course you can always set up free accounts with Google or Yahoo.

Can you have two separate iPods on iTunes without having the same songs?

My husband and I both have iPods but we don't want to same music on them. Really we would like to have two separate iTunes, so that I don't get his music and he doesn't get mine. Is that possible or do we just have to manually sync them?

HT2542 Can we have two separate itunes accounts using the same mac?

I am wanting to download music to my Thunderbolt smart phone (i know, no iphone yet, next upgrade) and I want to use itunes to do it. My partner has an itunes account and I thought I opened my own itunes account, but apparently I didn't. I don't like the same music and only want to download music I like to my phone. Can we just have one account and be able to download checked music from the itunes to multiple devices?

I'm confused

Do you want one or two?
By the way, and iTunes account is really the thing you use online to purchase music, not what you have on a computer. You have user accounts on a computer, and you have iTunes libraries or collections of media. You can have multiple user accounts on a computer. You can have a single or multiple user accounts use a single or multiple libraries. We need to know exactly what it is you have/want.

Hi, Can anyone tell me if you can have two separate itunes accounts on one laptop?

Hi, Can anyone tell me if you can have two separate itunes accounts on one laptop? If so can you please let me know how I set this up. I already have my itunes account loaded on and have another on a separate hardrive that I want to be able to use on the same laptop. many thanks.

Are you meaning 2 different accounts or 2 different libraries?
Launch iTunes with the 'Option' key held down and follow the dialog as to which library you want to open.

Copy the content from one computer to another and import the media into iTunes.
Any playlists, playcounts, etc on the computer the content is being moved from will be lost.
