What is 66 level number in COBOL?

You must use the level number 66 for data description entries that contain the RENAMES clause. A level-66 entry cannot rename another level-66 entry, nor can it rename a level-01, level-77, or level-88 entry. One or more RENAMES entries can be written for a logical record.

What is level 88 in COBOL?

COBOL can define a set of level-88 elements, which list potential values for the preceding element. The level-88 statements can be used to test the value of the preceding element. For example, if the element FLAG1 has a value of ‘Y’, then FLAG1-ON resolves to true when used to test the value of FLAG1.

What is the function of level 66 mainframe?

66 level – Used for RENAMES clause. and 66 levels should not have a picture clause. Example – 01 EMP-REC.

What are 88 levels?

Level 88s are used to assign names to values at execution time. Thus, a condition-name is not the name of an item, but rather the name of a value. A level 88 doesn’t reserve any storage area. Each level 88 must be associated with a data item and must immediately follow that item in the Data Division.

In RM/COBOL, the ON SIZE ERROR condition exists when the value resulting from an arithmetic operation exceeds the capacity for the associated data item.

What is PIC 9 COBOL?

The most common ones are: PIC X for strings. PIC X(100) means a 100-byte string. PIC 9 for numbers, optionally with S (sign) or V (implicit decimal point). For example, PIC S9(7)V99 means a signed number with 7 digits to the left of the implicit decimal point and 2 digits to the right.

What is FD in mainframe?

What is Flag in COBOL?

When you use condition-names to give more than just on or off values to a field, the field is generally referred to as a flag . Flags and switches make your code easier to change. If you need to change the values for a condition, you have to change only the value of that level-88 condition-name.
