Language Summary Tables

In the following tables, optional arguments for intrinsic procedures are enclosed between brackets: [optional arg]. The argument names given in the tables are the keyword names. Keywords allow you to specify optional arguments without regard to order. For example, when invoking PRODUCT(ARRAY [, DIM][, MASK]), you can skip the argument DIM by using the statement: array3 = PRODUCT(array1, MASK = array2).

• Program Unit Calls and Definition
