CHAR is fixed length and VARCHAR is variable length. CHAR always uses the same amount of storage space per entry, while VARCHAR only uses the amount necessary to store the actual text. CHAR is a fixed length string data type, so any remaining space in the field is padded with blanks. CHAR takes up 1 byte per character.

How do I find the length of a VARCHAR in COBOL?

You can use the LENGTH function in many contexts (including numeric data and tables) to determine the length of string items. Length(Customer-Name) or LENGTH OF Customer-Name returns the same result: the length of Customer-Name in bytes. You can use the LENGTH function only where arithmetic expressions are allowed.
