RE: Subfile loading time tips needed

Yep, this can be done in RPG.

However, your program type will change from RPGLE to SQLRPGLE.  I
recently began using it and I find it a good alternative to
CHAIN/READ/ETC.

Here's a sample from one of my RPG programs (there are two ways to do
this - either via a pre-defined SQL statement or through a direct
statement):

Pre-defined:
/free
    SQLstmt = 'select partno, partcl, serialno, pqty into :partno,
:partcl, :serialno, :pqty';                
    SQLstmt = SQLstmt + 'from PQR_PF '
    SQLstmt = SQLstmt + 'WHERE PQSTATUS =' + apos + 'RLSD' + apos;
 /end-free                   
C*                           
C/Exec SQL                   
C+ EXECUTE IMMEDIATE :SQLstmt
C/End-exec                   
C*                           

Direct Statement:
C*                                                
C/Exec SQL                                        
C+ SELECT MAX(CONCAT(otkdf2,otkdf3)) into :LASTN1M
C+ FROM SST32 WHERE otisn0= :plcd                 
C+ AND otisn2 = 'PS'                              
C+ AND ottlcd = :PTLCD                            
C+ AND otpsts = 'M'                               
C/End-Exec                                        
C*                                                

HTH,

Brian.
