accessing variables in arrays

[Guest_imported]

If i had an array

array = (red,yellow,blue)

With the array values separated by commas

How would I access say the value blue , Say to do a Conditional

Ex.
if ($array[2]==blue)
echo color is blue

I used this, But It gives me script out of range

The array values must be separated by spaces.
Add the line

set array = ( `echo $array | tr ',' ' '` )

after the first initialization of array to recreate the variable value whith all ',' (commas) translated to ' ' (spaces).
