Via Christi Health has opted out of the Wichita school districtâs health insurance network, a move that is expected to send more than 1,000 teachers and other employees scrambling to find new primary care doctors. âIt is causing some panic,â said Shannon Krysl, head of human resources for the Wichita district.
PL/Perl Functions and Arguments. To create a function in the PL/Perl language, use the standard CREATE FUNCTION syntax: The body of the function is ordinary Perl code. In fact, the PL/Perl glue code wraps it inside a Perl subroutine. A PL/Perl function must always return a scalar value.
As a result PERL is forced to count through each element and return a value representing the array. Adding elements is a breeze, we use the following functions to add/remove and elements: 1  push() - adds an element to the end of an array.  unshift() - adds an element to the beginning of an array.
