Count of array variables.

[gawker]

Hi,

If an array has been created in an awk process via the split command, is there a variable that reports on the number of array entries?

I can get the information by reading the array with "while", but figure there must be a more direct way of getting the value.

Thanks!

split returns the number of array elements it creates, so you just need something like

n1 = split($0,a)

and n1 would be the number array elements created. CaKiwi

split (s,a[,fs])
Split the string s into array elements a[1],
a[2],..., a[n], and return n. The
separation will be done with the extended
regular expression fs or with the field
separator FS if fs is not given.

n = split (ENVIRON["PATH"], path, ":&quot
for (i = 1; i <= n; ++i)
print path
