QMHSNDPM is likely the API I use the most in my ILE RPG programs to send escape or info messages.

F.E.

D SndPgmMsg       PR                  ExtPgm('QMHSNDPM')     
D  MsgId                         7    Const                  
D  QualMsfF                     20    Const                  
D  MsgData                    9999    Const Options(*varsize)
D  MsgDataLen                   10i 0 Const                  
D  MsgType                      10    Const                  
D  ToCSE                        10    Const Options(*VarSize)
D  ToCSECtr                     10i 0 Const                  
D  MsgKey                        4                           
D  ErrCode                        *   Const                      
...
 /free
   ...
      Msg = This is a test to cancel the program';
      MsgKey = ' ';
      sndpgmmsg( 'CPF9898' : 'QCPFMSG   QSYS'
                           : Msg       : %Len(Msg)       
                           : '*ESCAPE' : '*'             
                           : 0         : MsgKey          
                           : *Null);
  /end-free

QCMDEXC is probably the one I've used most.
Allows you to run CL commands from an RPG program, like changing library lists or overriding files or submitting jobs...

 

[PeteJohnston]

As an alternative to QCMDEXC you can use QCAPCMD. It does exactly the same but it uses the API error structure to return any errors found while executing the command. My favorites are QDBRTVFD and QUSRMBRD which give you ALL of the information you would ever want about any physical file.
