Wrong proc! The function you are trying to use is part of proc fedql. For, example, try the following:

data afewords;
 input Word1$ Word2$ ;
 cards;
*some/ WHERE
*every* THING
*no* BODY
;

proc print data=afewords;
run;

proc fedsql;
 select trim(both '*' from strip(word1))
 from afewords
 ;
quit;

proc fedsql;
 select trim(leading '*' from strip(word1))
 from afewords
 ;
quit;

proc fedsql;
 select trim(trailing '*' from strip(word1))
 from afewords
 ;
quit;
