A
Correct answer
Explanation
Standard JCL allows a maximum line length of 71 bytes for the actual JCL statements (columns 1-71). Column 72 is for continuation, and columns 73-80 are for sequence numbers. This is a well-documented JCL constraint.
AI explanation
A JCL statement's usable data occupies columns 1 through 71 (71 bytes), since column 72 is reserved as a continuation indicator and columns 73-80 are reserved for optional sequence/identification numbers. That's why 71 bytes, not 72, is the maximum length of the actual statement content on one line.
