Hereof, what is an Evaluate statement?

EVALUATE Statement. The EVALUATE statement causes multiple conditions to be evaluated. The EVALUATE/CASE construct provides the ability to selectively execute one of a set of instruction alternatives based on the evaluation of a set of choice alternatives.

Secondly, what is inline perform in Cobol? Inline Perform: It performs a set of Cobol statements between Perform & END-Perform.

What is the difference between continue and next sentence in Cobol with examples?

NEXT SENTENCE gives control to the verb following the next period. CONTINUE gives control to the next verb after the explicit scope terminator. (This is not one of COBOL II's finer implementations). It's safest to use CONTINUE rather than NEXT SENTENCE in COBOL II.

What is the use of evaluate statement in Cobol?

EVALUATE provides a multi selection control during the program execution. EVALUATE used to validate multiple conditions in a single shot. EVALUATE statement in COBOL is similar to Case or Switch statements of other languages. EVALUATE can do multiple IF conditions task.

How do you remove leading spaces in Cobol?

What is reference modification in Cobol?

MOVE reference modification is special purpose and used to move part of data from source field to target field. MOVE reference modification defines the below two items to move the partial data to target field. In move reference modification first position indicates the starting position.

Is numeric check in Cobol?

the numeric class check is only valid on pic 9 display and packed-decimal type fields. anytime you use reference modification, the field type is automatically x - alphanumeric. │ one or more signed elementary items. so you can do NUMERIC test on a group as long as none of the elementary items are defined as S9

What is delimited by size in Cobol?

DELIMITED BY SIZE used in STRING concatenation. The string will concatenate with the same size of the input identifiers/literals. Entire source string will be moved to the destination field.

What is inspect in Cobol?

How do you reverse a string in Cobol?

Have the string you want to reverse, in a data-item. Define a data item (or) a table to store the reversed string. PERFORM a loop, with a data-item whose value is the length of the string, decremented by 1 in each iteration, until the data-item's value reached zero.

What does exit do in Cobol?

EXIT Statement - COBOL. The EXIT statement provides a common end point for a series of procedures. The EXIT PROGRAM statement marks the logical end of a called program. The EXIT PERFORM statement provides a means of exiting an in-line PERFORM (with or without returning to any specified test).

A table/Array is a set of similar items which are combined logically and each item should has the similar data definition/description as the other items in the set. In detail, an array/table contains the data items which are having same in type, length and declaration which are to be repeated/non-unique.

Do while loops Cobol?

Use a DO WHILE loop when you want to execute the loop while a condition is true. DO WHILE tests the condition at the top of the loop. If the condition is initially false, the loop is never executed. You can use a DO WHILE loop instead of the DO FOREVER loop in the example using the LEAVE Instruction.
