Syntax -

SET index-name    TO initial-value

Example -

Increasing or decreasing table indexes -

SET statement is also used to increase the index (UP BY) or decrease the index (DOWN BY).

Syntax -

SET index-name    UP BY   increment-value

SET index-name    DOWN BY decrement-value

Example -

SET WS-INDEX    UP BY 1

Parameters -

  • increment-value - The increasing value from the current index value. From example, it is 1.
  • decrement-value - The decreasing value from the current index value.

Setting the condition name to true or false -
