The video tutorial explains the Cat X function, highlighting its ability to remove leading and trailing blanks, use delimiters for concatenation, and compares it with the Cat function. A practical example demonstrates how to concatenate first and last names using Cat X, emphasizing its advantages over the Cat function, which does not remove blanks.

What is the purpose of using a delimiter in the CatX function?

• To join strings together with a specified character

• To remove characters from strings

• To convert strings to lowercase

What is a key difference between the CatX and Cat functions?

• CatX adds extra spaces between strings

• CatX can only concatenate numbers

• CatX removes leading and trailing blanks, while Cat does not

• Cat can only concatenate strings with spaces

Which function would you use to concatenate strings without removing blanks?
