Control then passes to the next statement at the same or less indented level as the IF statement (other than related ELSE-IF or ELSE statements which, by definition, are at the same level as their IF). Example: “When writing a COBOL program, I follow a proper structure and formatting that helps in properly implementing a code. The logic can be difficult to follow, although explicit scope terminators and indentation help. When an IF statement contains an IF statement as one of its possible branches, the IF statements are said to be nested. . Java Nested if else Statement.

Selection COBOL uses the IF statement for selection. The statement inside IF block will not execute when the condition of IF statement is false. ?this statement can itself be a conditional. NEXT SENTENCE unconditinally transfers control to the end of the current sentence. Nested IF statements are considered to be matched IF, ELSE, and END-IF combinations proceeding from left to right. If nested, by an ELSE phrase associated with an IF statement at a higher level of nesting. Loop Statements in COBOL: Simply put, loops in COBOL are carried out using the PERFORM verb but it has other functions that are worth mentioning here. In its simplest form, PERFORM merely transfers control to a block of code that will be executed just once.
