Mainframe, MVS and zOS Discussion

Hi,

How can we display the value of a variable defined at level-88? Please help, I could not reply this question in the interview.

You cannot display the value of a level 88 since it never, under any circumstances, has a value. You display the value of the variable the level 88 is associated with. Level 88 are called conditionals in the Language Reference manual since they are not true variables. A variable can be used in MOVE, COMPUTE, and other statements while a level 88 can only be tested with the IF statement, or be set by using the SET statement.

Thank you so much Robert. I have used this answer in my recent interview.
