Hi Brian,

A codesnippet of the DDS what I usually use is:

 * Subfile control
A          R ALG012AC                  SFLCTL(ALG012AS)        
A                                      WINDOW(ALG012W)         
A                                      OVERLAY                 
 
 * Window definition
A          R ALG012W                                              
A                                      KEEP                       
A                                      WINDOW(4 20 15 55)         
A                                      WDWBORDER((*COLOR BLU) (*DSPATR
RI)-
A                                       (*CHAR '        '))       

 * Remove window from screen
A          R ALG012RMV                 CLRL(*NO) OVERLAY FRCDTA   

 * No i/o to this record, it's only here to prevent 
 * screen clearing at init time
A          R ALG012ASS                 ASSUME                     
A                                  2  2' '                        

Compile your display file with RSTDSP(*NO) DFRWRT(*YES).
I do a write to the remove record when returning to the caller.
