It is used for searching a character string and as soon as string is found it will return it.
Proc Summary is same as Proc Means i. PROC contents tells the structure of the data set rather than the data values. The functions of Procglm are covariance analysis, variance analysis, multivariate and repeated analysis of variance.
An informat is an instruction that SAS uses to read data values. They are used to read, or input data from external files. CATX syntax inserts delimiters, removes trailing and leading blanks and returns a concatenated character string.
PROC gplot identifies the data set that contains the plot variables. It has more options and therefore can create more colorful and fancier graphics. Input Function: Character values are converted into numeric values Put function: Numeric values are converted into character values. Single Dash specifies consecutively numbered variables. Double Dash specifies variables available within that data set.

If you are frequently performing statistical analysis, we would strongly urge you to consider making each one of these packages part of your toolkit for data analysis.
The common theme relating the many applications of the software is time series data: Compressing a data set reduces its size by reducing repeated consecutive characters or numbers to 2-bye or 3-byte representations. The disadvantages include not being able to use SAS observation number to access an observation. If there are few repeated characters, a data set can occupy more space in compressed form than in uncompressed form, due to the higher overhead per observation.
