Processing Table Items

You can process alphanumeric or numeric table items using intrinsic functions as long as the table item's data description is compatible with the function's argument requirements. The ILE COBOL for AS/400 Reference describes the required data formats for the arguments of the various Intrinsic Functions.

Use a subscript or index to reference an individual data item as a function argument. Assuming TABLE-ONE is a 3X3 array of numeric items, you can find the square root of the middle element with a statement such as:

       COMPUTE X = FUNCTION SQRT(TABLE-ONE(2,2)).
