Example

  pjs.define("i", { type: 'integer', length: 3, decimals: 0, initValue: 1 });
  pjs.define("SRCHWD", { type: 'char', length: 1 });
  pjs.define("arr", { type: 'char', length: 1, dim: 10, orderby: 'ASCEND' });

  arr[1] = 'A';
  arr[2] = 'B';
  arr[3] = 'C';
  arr[4] = 'C';
  arr[5] = 'C';
  arr[6] = 'D';
  arr[7] = 'E';
  arr[8] = 'E';
  arr[9] = 'F';
  arr[10] = 'G';

  SRCHWD = 'D';

  pjs.lookupLT(SRCHWD, arr, i, { low: 55 });
