ConditionsA condition is a special piece of code that allows you to instruct the computer to compare two pieces of data. Conditions are used in IF statements and in the While/Until clauses of the PERFORM statementConditions have the syntax:data-1 operator data-2 where data-1 and data-2 can be a literal or a field. data-2 can also be a COBOL literal such as SPACES or ZEROS.Operator can be the traditional comparison symbols =, , =. To check for inequality use 'NOT =' since not all compilers accept the symbol . Rarely, a compiler will not accept =. You can use 'NOT >' and 'NOT
