To answer this question, you need to understand the concept of screen size in CICS BMS (Basic Mapping Support).
In CICS BMS, the screen size is specified by two dimensions: the number of rows and the number of columns. The screen size determines the maximum number of characters that can be displayed on the screen.
Let's go through each option to understand why it is correct or incorrect:
Option A) 32 x 72 - This option is incorrect because the correct answer is 24 x 80, not 32 x 72.
Option B) 24 x 72 - This option is incorrect because the correct answer is 24 x 80, not 24 x 72.
Option C) 32 x 80 - This option is incorrect because the correct answer is 24 x 80, not 32 x 80.
Option D) 24 x 80 - This option is correct because the screen size in CICS BMS is typically defined as 24 rows and 80 columns. This means that the maximum number of characters that can be displayed on the screen is 24 rows multiplied by 80 columns, which equals 1920 characters.
The correct answer is D) 24 x 80. This option is correct because it represents the standard screen size in CICS BMS.
