Hi everyone and advance thanks for those would help. Here's my script, p.csv is a multi row/line file. I get the error "array reference out of bounds!" after it has read the whole file.
- - - - - - - - - - -
Dim $Line[39]
If Open(1,"p.csv",2) = 0
WHILE @ERROR = 0
$Line = Split(readline(1),",")
? $Line[0] + $Line[3] + $Line[19] + $Line[21]
LOOP
endif

The p.csv file has 39 columns/elements. The script above displays columns 0,3,19 and 21 properly up to the very last row of data then displays the error above plus the line "? $Line[0] + $Line[3] + $Line[19] + $Line[21]". I should have added that earlier.

I got it, i added an "if $Line[0] = "" goto end1 endif" after the split command and that did the trick. i was getting the out of bounds error because it has reached the end of the row and there was nothing to display.

I added the line "? @error" after the split line and never got a value > 0. When I tried to redirectoutput to file there was a blank line at the top. Is that normal?

Yes, you're telling it to print a line by using ?
Here is some untested code to remove blank but still should do similar as Rad has already shown you.
Code:
WHILE @ERROR = 0
$Line = Split(readline(1),",")
If $Line
$Line[0] + $Line[3] + $Line[19] + $Line[21] ?
EndIf
LOOP
This would get rid of a blank but would still error if one of the elements of your array was empty
because you're telling it to use or show something that does not exist which generates the error.

I don’t think it is necessary to define $Line as an array because I think the ‘Split()’ function does that for you every time it is used.
Code:
Dim $Line,$Element,$Output
$Output = ""
If Open(1,"p.csv",2) = 0
While @ERROR = 0
$Line = Split(ReadLine(1),",")
If $Line
For Each $Element in $Line
$Output = $Output + $Element
Next
? $Output
EndIf
Loop
EndIf

benny your code doesn't actually do what he is trying to do, but I decided to golf it anyways 
Code:
Dim $Element,$Output
if 0 = Open(1,"p.csv")
do
For Each $Element in Split(ReadLine(1),",")
$Output = $Output + $Element
Next
? $Output
until @ERROR
EndIf
