Use the SCAN function. which separates a character expression into words and returns the Nth word SCAN( argument, n <,delimiters> ) where argument is a valid SAS character expression, n is a valid SAS numeric expression, and delimiter is the character(s) you wish to use to delimit words.

If delimiter is omitted, the following are treated as delimiters (on ASCII systems) blank . < + | & ! $ * ) ; ^ / , % > \

Since you are parsing a name which could have embedded periods, to explicitly follow the rule you describe would require

username= 'lastname, firstname' ; *sample data;

lname = scan(username,1,','); fname = scan(username,2,',');
