[TYPO3] get a var in URL with typoscript

[Mike Morris]

Hi all,

i have an url like  index.php?firstLinkID=123&b=456&L=1

If I use conditions in TS ic can do it this way:
[globalVar= GP:L=1]
  stuff here...
[global]

But I have a dataWrap on something, I would like to get the A variable into 
my datawrap, maybe like this:
.dataWrap = <a href="index.php?id={firstLinkID}">link</a>

Is this, or something similar possible?

Sorry, but can't use any userfunc here...

Thanky
