Return Value
Function will return 0 if no matching element has been found, otherwise it will return the element index.
Example
pjs.define("i", { type: 'integer', length: 3, decimals: 0 });
pjs.define("SRCHWD", { type: 'packed decimal', length: 2, decimals: 0 });
pjs.define("arr", { type: 'char', length: 15, dim: 10 });
arr[1] = 'Cornwall';
arr[2] = 'kingston';
arr[3] = 'London';
