Variable name incrementing in iterations

I'm parsing each line of a text file to see if it contains a 'name=xxx' parameter. If so, I strip out everything but that 'name' parameter value. I want to put the first 'name' parameter value that I find in a variable called $Book1, the second one $Book2, etc. Is there a way to increment a variable name with every iteration? I know you can increment a variable *value*, but what its *name*?
Thx
Ron

Oh right! So set up a Books array, and then put the first name in Books[0], the second one in Books[1], etc., right?

Thats it exactly.
If you don't know how big the array will be, you can create it dynamically.
There are a lot of ways of doing it, but here's one.
Take a file "bookfile.txt" with the following contents:
Code:
name=Withering Bites
name=Hairy Otter and the Fragrant rice of Doom
name=20 Leeks under the Pea
This code will load the values into an array, then display them:
Code:
If Not Open(1,"bookfile.txt")
$s=ReadLine(1)
While Not @ERROR
If InStr($s,"name=")=1
If IsDeclared($aBooks)
$aBooks=Split(Join($aBooks,"|")+"|"+SubStr($s,6),"|")
Else
$aBooks=Split(SubStr($s,6),"|")
EndIf
EndIf
$s=ReadLine(1)
Loop
$=Close(1)
EndIf
For $i = 0 to Ubound($aBooks)
$i+1 " " $aBooks[$i] ?
Next

you can use Readfile() to read a textfile into an array
then use filterarray() to filter out every line without 'name=' on it
