SAS functions can be used to convert data and manipulate
character variable values.
different types of functions:1)TRIM
2)SUBSTR
3)ABS
4)SCAN
TRIM:Removing the trailing blanks from character expressions.
syntax=trim(argument)
substr:extracts the substring from an argument
syntax=substr(argument,position<,n>)
