How to solve Subscript out of range?
Hi everyone
I want to compare numbers line by line
Example
array = 12 15 15 19 14

I have code:
Code:
#!bin/csh
set a = 1
set b = 2
while($a<6)
if($array[$a] == $array[$b])then
echo "EQUAL"
else if($array[$a] < $array[$b])then
echo "SMALLER"
else 
echo "BIGGER"
endif
@ a = $a + 1
@ b = $b + 1
end

Output:
Code:
SMALLER
EQUAL
SMALLER
BIGGER

How to solve it?

I'm not familiar with csh but it seems that you're trying to access a non-existing element of the array (comparing array[5] with array[6]).
