Hi,
In fact, Evaluate constructs case structure. we can also replace it by using nested if. It is simple in use with less complexity

EVALUATE statement contrusts a case structure. The explicit scope terminator for EVALUATE is END-EVALUATE. The various cases can be places between the EVALUATE and END-EVALUATE statements.

Example:

Here SQLCODE is a built in variable name

EVALUATE SQLCODE
     WHEN 0
                DISPLAY ' FETCHED RECORDS'
     WHEN 100
                DISPLAY ' NO RECORDS FOUND'
     WHEN OTHER
                DISPLAY ' SQL ERROR CODE :' SQLCODE
END-EVALUATE
