I wanna define a variable 'tempbase'. Therefore I read a text file "base.out". "base.out" contains a list with four columns. 'tempbase' is the 4th entry in the line, where the first entry is equal to the predefined variable $orb1 and the second entry is equal to $orb2. I wrote the code below, but it doesn't work:
$1 gives you the first entry of file baseout and it gets stored in $orb1
$2 gives you the second entry of file baseout and it gets stored in $orb2
$4 gives you the forth entry of the file baseout and it gets stored in $tempbase
