The format is Print Len (“Phrase”) Output 6 For example, Len (VisualBasic) = 11 and Len (welcome to VB tutorial) = 22 The Len function can also return the number of digits or memory locations of a number that is stored in the computer. For example, Private sub Form_Activate ( ) X=sqr (16) Y=1234 Z#=10# Print Len(x), Len(y), and Len (z) End Sub will produce the output 1, 4 , 8. The reason why the last value is 8 is because z# is a double precision number and so it is allocated more memory spaces. • (ii) The Right Function • The Right function extracts the right portion of a phrase.
