BUILT-IN FUNCTIONS


It is not necessary to assign a function with no return value to a dummy variable. For example, insteady of the following:
  dummy = Push_banner(text)
you may use the following:
 Push_banner(text)
This applies to all user-defined functions, all the run-time library functions, and the following built-in functions:
 Begin_status
 End_status
 Find_file_end
 Modify_banner
 Put_def_db
 Push_banner
 Pop_banner
 Put_banner
 Remove_banner
 Status
 Set_logical
 Set_symbol
The remainder of this chapter contains descriptions of all the built-in functions.
