Can you explain the clause ‘IS NUMERIC’?
This clause helps to ensure if there is any kind of item which is numeric. It returns TRUE when the items opposite to it contains only numbers (0-9). Remember the number can either be negative or positive.
Please explain the use of level 66 and 88?
In COBOL language every level holds an importance. Talking about such levels; Level 66 contributes in RENAMES clause whereas Level 88 is essential for condition names.
Is there any difference between the Index and subscript?
The explanation for this is pretty simple. Interviewer is trying to simply understand if you have knowledge about all these topics. Subscript is known for the array occurrence where as Index is known for the displacement from starting of an array.
