Like functions, CALL routines perform actions, based
on the
values of arguments that are supplied with the routine name. However, unlike
functions, CALL routines do not return values. Many halt the program if the
call is unsuccessful. Use CALL routines to implement features that do not
require return codes.
SCL has a variety of CALL routines of its own. It also
supports all of the CALL routines that are provided by the Base SAS language.
