What are the correct values for the DSN parameter of a temporary data set?
-
&NAME&(TEMP)
-
&&TEMP(NAME)
-
&&NAME
-
&NAME
In JCL, temporary data sets are designated by double ampersands (&&). Valid formats include a simple name like &&NAME or a partitioned data set member like &&TEMP(NAME). Formats with a single ampersand represent symbolic parameters instead of temporary datasets.
To answer this question, we need to understand the format and usage of the DSN parameter for a temporary data set.
The DSN parameter is used to specify the name and characteristics of a data set in a JCL (Job Control Language) statement. Temporary data sets are typically used for temporary storage during the execution of a job and are deleted automatically after the job completes.
Let's go through each option to understand why it is correct or incorrect:
Option A) &NAME&(TEMP) - This option is incorrect because it does not follow the correct format for a temporary data set. The correct format for specifying a temporary data set is &&TEMP(NAME), where TEMP is the generic name and NAME is the specific name.
Option B) &&TEMP(NAME) - This option is correct because it follows the correct format for a temporary data set. The double ampersand (&&) indicates that it is a temporary data set, TEMP is the generic name, and NAME is the specific name.
Option C) &&NAME - This option is correct because it follows the correct format for a temporary data set. The double ampersand (&&) indicates that it is a temporary data set, and NAME is the specific name.
Option D) &NAME - This option is incorrect because it does not follow the correct format for a temporary data set. The double ampersand (&&) is missing, which indicates that it is not a temporary data set.
The correct answer is Option B and Option C. These options are correct because they follow the correct format for specifying a temporary data set in the DSN parameter.
