PROCOPT cannot be used on PCB and SENSEG.
B
Correct answer
Explanation
PROCOPT (Processing Option) is a parameter that can be used with both PCB (Program Communication Block) and SENSEG (Sensitive Segment) statements in IMS PSB (Program Specification Block) generation. It defines what operations (GET, Insert, Replace, Delete) a program can perform on specific database segments. The statement that it cannot be used is false.
