IF SEX=1 can also be coded as IF MALE in Procedure division. If multiple values are coded on VALUE clause, the first value will be moved when it is set to true.This clause can be specified with alphanumeric and alphabetic items for right justification. OCCURS Clause is used to allocate physically contiguous memory locations to store the table values and access them with subscript or index.A set of computerized business procedures in an application area is called information systems. When your program moves from one computer to another computer, the only section that may need to be changed is ENVIRONMENT division. Redefining declaration should immediately follow the redefined item and should be done at the same level. Size of redefined and redefining need not be the same. The word COBOL is an acronym that stands for COmmon Business Oriented Language. They are ZERO/ZEROS/ZEROES, QUOTE/QUOTES, SPACE/SPACES, ALL, HIGH-VALUE/HIGH-VALUES, LOW-VALUE/LOW-VALUES.
