What paragraph can be used in COBOL to define a unique collating sequence or unique addressable character sets?

Mainline

Collate

Sequence

Class

Special-Names

Question 3 2 pts

What is wrong with the following code setup:

01 CARTYPES PIC 99 VALUE ZEROES.

   88 FORD PIC 99 VALUE 01.

   88 DODGE PIC 99 VALUE 02.

   88 MAZDA VALUE 03.

   88 HONDA PIC 99 VALUE 04.

Syntax is correct, code would compile

MAZDA does not have a PICTURE clause

PIC should not be on 88 levels

VALUE should be SPACES

VALUE clause should not be on 88 Levels

Question 4 2 pts

Evaluate the following code what would the response be:

01 VALIDCLASSCODES PIC 99 VALUE ZEROES.

   88 CISCLASSES VALUE 10.

88 LITCLASSES VALUE 20.

   88 MATCLASSES VALUE 30.

88 PHYCLASSES VALUE 40.

(Input VALIDCLASSES = 20)

CISCLASSES

PHYCLASSES

LITCLASSES

MATCLASSES

Answer 1

Answer:

All the symbols we can use in Cobol.

Special-Names paragraph can be used to define a unique collating sequence.

PIC should not be on 88 levels. 88 level number always associated with any other level number 01-49. No PICTURE clause should be in 88 level numbers.

IF statement is the selection structure. We use IF statement to select statement if true this then this. We are selecting statement in this. That’s why it is called Selection Structure.

For an IF statement syntax we need- (.) Period or END-IF, ELSE, IF-THEN, NEXT SENTENCE

There is no limit for IF statements in a NESTED IF Statement.

This code will display 5. Because there is one condition IF WS-COUNTER =1 and in a program, we are adding value 1 to WS-COUNTER, it has value 1 condition is true then the next statement is MOVE 5 TO WS-STATUS. It stores 5 in WS-STATUS and displays this.

This code will display 0. Because WS-COUNTER is not greater than 1 or not equal to 2 then it will nothing store in WS-STATUS. There are two conditions and they are false so it will not proceed next statements.

In last question. I am not understanding that what you want to execute in IF statements, I am answering here the only basis of IF statement, I am telling you when IF statement will give result TRUE. With AND IF both conditions true then it will return TRUE. IF one of them is false it will return FALSE. With OR only one should be TRUE to return TRUE. If both false then it will return FALSE.

1.IF true   or   true   ß true result (This statement will give TRUE).

2.IF true   or   false  ß true result  (This statement will give TRUE).

3.IF false or   true  ß true result     (This statement will give TRUE).

4.IF false or   false  ß false result    FALSE

5.IF true   and true  ß true result     (This statement will give TRUE).

6.IF true   and false  ß false result     FALSE

7.IF false and true  ß false result       FALSE

8.IF false and false  ß false result      FALSE
