How do you change the datatype of a variable in SAS?
SAS uses the BESTw. format, where w is the width of the character variable and has a maximum value of 32. You cannot change the type of a variable. You will need to create a new variable from the old variable with the new data type and then drop and rename to keep the original names.
What is Proc SQL in SAS?

How do I create a character variable in SAS?
You can use the LENGTH statement to create a new variable and explicitly set its length. Important: Place the LENGTH statement first in the DATA step before any other statements that reference the variable. The maximum length of any character variable in SAS is 32,767 bytes.
What is difference between informat and format?

How do I concatenate a character variable in SAS?
How to Concatenate Strings in SAS (With Examples)
- Method 1: Concatenate Strings with Space in Between new_variable = CAT(var1, var2);
- Method 2: Concatenate Strings with No Space in Between new_variable = CATS(var1, var2);
- Method 3: Concatenate Strings with Custom Delimiter. new_variable = CATX(“-“, var1, var2);
