16) What is the use of 66 and 88 levels in COBOL?
Level 66: It is used for Renames clause.
Level 88: It is used for condition names.
17) What is "IS NUMERIC" clause?
"IS NUMERIC" clause: It is used to check the item is numeric or not. It returns true if the item contains only numbers (0 to 9). Here, the item can be positive or negative.
18) What is scope terminator?
scope terminator: It is used to mark the end of a verb.
Example: If and End-If
