Call RPG Service Program from CLLE

["Marvin Radding" <MRadding@xxxxxxxxxxxx>]

I am using the ISTKT and attempt to use the MSGTKT.  I want to send
error messages to the display file via the SNDMSG service program.  

I call SETDFTPGMQ:

CALLPRC    PRC(SETDFTPGMQ) PARM('RMR00100C')

I call SNDMSG:

CALLPRC    PRC(SNDMSG) PARM('CPD006' '    Invalid +  
             Function Key') RTNVAL(&MSGKEY)          

I have the MSGSFL defined:

A          R SFLHDR                    SFL                      
A                                      SFLMSGRCD(24)            
A            MSGKEY                    SFLMSGKEY                
A            PGMQ                      SFLPGMQ(10)              

I have the MSGSFLCTL defined:

A          R HEADER                    SFLCTL(SFLHDR)           
A                                      SFLDSP       
A                                      SFLDSPCTL    
A                                      SFLINZ       
A  99                                  SFLEND       
A                                      SFLSIZ(0002) 
A                                      SFLPAG(0001) 
A            PGMQ                      SFLPGMQ(10)  
A            #POSITION      4S 0H                   
A            #FIELD        10A  H                   
A            #RECORD       10A  H                   
A                                  1  3DATE         

Can anyone see what I am missing.  I see no messages at the bottom of
the screen except when the system displays job complete messages.

Before I lose what little hair I have left, can anyone help?
