getting 'vowel' out of my output

[Simmy]

Question:
My input looks like this:
VOWEL,OPENING,PLACE,ENVIRONMENT.
U,3,2,C.
I,3,2,S.
...
I want to count the different vowels but 'VOWEL' itself may not be in the output.
I had this script:
BEGIN {
FS=","
}
{
vowels [$1]++
}
END {
delete vowels[vowel]
for (vowel in vowels)
printf("%s\t%d\n", vowel, vowels[vowel])
}
Why is 'VOWEL' still in my output?
How can I solve this problem?

simmy,

When I run your script, I get

I   1
U   1

as expected. What output you want?
BTW, the statement

delete vowels[vowel]

is trying to delete non-existant element 0 from the vowels array and is unnecessary.

Hope this helps. CaKiwi

CaKiwi,

Yes, your output is what I want but mine is still:

U 1
I 1
VOWEL 1

My script takes the first field of my input as a vowel, doesn't it?

What about this ...

BEGIN {
FS=","
}

$1 != "VOWEL" {vowels [$1]++}

END {
delete vowels[vowel]
for (vowel in vowels)
printf("%s\t%d\n", vowel, vowels[vowel])
}

I somehow completely missed the line
VOWEL,OPENING,PLACE,ENVIRONMENT.
in your input despite the fact that it was capitalized. :~/. Grega's solution looks good, but it seems to me that the delete line is still superfluous. CaKiwi
