I run the above codes using SAS 9.3, but got the following error:

369 valuesdisplay = ("0" "5" "10" "25" "50" "100"); /* labels displayed */
------------- ---
1 22

WARNING 1-322: Assuming the symbol VALUES was misspelled as valuesdisplay.
ERROR 22-322: Syntax error, expecting one of the following: a numeric constant,
a datetime constant, (.
ERROR 76-322: Syntax error, statement will be ignored.

Could you point me what's wrong?
