To answer this question, we need to understand the syntax and format of the DISPLAY statement in COBOL, as well as the data type and picture clause used for the CTR variable.
In COBOL, the DISPLAY statement is used to display the value of a variable on the output device. It does not alter the value of the variable.
The CTR variable has a picture clause of S9(4)V99, which means it is a signed numeric variable with a total length of 6 characters, including 2 decimal places.
The value assigned to CTR is -1234.55.
Therefore, when the statement DISPLAY CTR is executed, the output will be "12345N".
Option A) 1234.55 - This option is incorrect because the DISPLAY statement does not change the value of the variable, and the value of CTR is -1234.55.
Option B) 12345N - This option is correct because the DISPLAY statement displays the value of CTR as "12345N" due to the picture clause used for the variable.
Option C) 12345E - This option is incorrect because the "E" format is not applicable to the CTR variable. The "E" format is used for floating-point variables, not signed numeric variables.
Option D) None of the above - This option is incorrect because option B is the correct answer.
Therefore, the correct answer is B) 12345N.
