AnswerClick to flip back
A
72
💡 Explanation:
Column 72 is used as the continuation indicator field in IBM mainframe assembly language. When a non-blank character appears in column 72, it indicates that the current statement is continued on the next line, allowing long instructions to span multiple lines while columns 73-80 are reserved for sequence numbers.
