Answer #1

PROC MEANS is used to calculate descriptive statistics such as mean, median, count, sum etc. It can also be used to calculate several other metrics such as percentiles, Quartiles, standard deviation, variance and sample t-test.

Proc contents Describes the structure of the data set rather than the data values. List the contents of one or more SAS data sets.

PROC DATASET is One of the simplest tasks that you can perform with PROC DATASETS is to output a list of datasets found in a SAS library.

The FREQ procedure will produce as many one-way tables as there are variables in the data set. Each table will include a count (frequency) of each unique value for each variable.
