////===== Description: ==================
//// Click into an line and execute this macro/script.
//// The line will split at tab stops 
//// and if an part is detected as an number
//// the greatest number is stored as vBiggestNumber for your use.


//// ====== Setting: ====================
//// Split line at tab. Use your own delimiter if needed:
SplitAt = "\t";


//// ====== Work: ======================
//// Get current line content:
document.selection.SelectLine();
CurrLine = document.selection.text;
//// Call function to split str and find biggest number:
vBiggestNumber = ReturnLargedNumber(CurrLine, SplitAt);


//// ====== End: =======================
//// Do something with the result:
alert('result: >' + vBiggestNumber + '<');
//document.selection.Collapse();
//document.selection.NewLine( );
document.selection.text = vBiggestNumber;


////======================================
////======== Function =====================
