clp何时应使用RCLRS,何时不用??

Question

有很多clp没用RCLRSC, 我也想请问clp中何时应该使用RCLRSC命令,何时不用它??

Answer 1

The resources that are reclaimed by this command are:
o  static storage
o  open files of object type *FILE                                 
o  user interface manager (UIM) application resources              
o  Common Programming Interface (CPI) Communications conversations
o  hierarchical file systems (HFS) resources               
o  user-defined communications sessions                                 
                                                                    
The RCLRSC command is not needed to reclaim the files and static   
storage of most programs, such as CL programs that end (return)     
normally, RPG programs that have the last record (LR) indicator set
on, and COBOL programs.  The RCLRSC command should not be used if it
might be processed while any COBOL program is still active in the   
application.
