In the syntax WORD(xxxx) what do xxxx specifies?
-
(a) starting characters of the name of the reserved-word table
-
(b) ending characters of the name of the reserved-word table
-
(c) alternate characters of the name of the reserved-word table
-
(d) All of the above
To solve this question, the user needs to know the syntax of the WORD function.
The WORD function is used in COBOL programming language to check if a given word is a reserved word or not. The syntax of the WORD function is:
WORD(word-to-be-checked, length-of-word-to-be-checked)
The xxxx in the given syntax WORD(xxxx) specifies the word to be checked for being a reserved word.
Option A, B, and C are incorrect because they do not specify the correct explanation for xxxx in the syntax WORD(xxxx).
Option D is incorrect because only option A is partially correct and option B and C are incorrect.
Therefore, the correct answer is:
The Answer is: A
In the COBOL compiler option syntax WORD(xxxx), xxxx represents the starting (leading) characters of the name of a reserved-word table that the compiler should use — it identifies which reserved-word table variant to activate by matching its name prefix. It's not the ending or alternate characters of the table name — the option is specifically documented as matching based on the beginning of the table's name. 'All of the above' is incorrect since only one of the specific descriptions (starting characters) is accurate.
