Hi,

can I use array elements ( all ) in conditional statements?
the problem is ,the total number of elements is not known.

e.g

A is an array with elements - 1,2,3

now if i want to test if the 1 st field of input record is either 1,2 or 3, i can do something like this

Code:

if ( $1 ~ /^A[1]$|^A[2]$|^A[3]$/) { print  YES }

but i want something like..

Code:

if ( $1 ~ /^A[1]$|^A[2]$|^A[3]$/| logical OR till array's last element) { print  YES }

Is that possibe?
