On given day COBOL will be efficient to access DB2 when compared to REXX.

Thanks for your reply
Cobol is better option but if you see i have to design a user input screen and it is a small applcation and changes are required in some times according to requirement
then what will you suggest and plese give some reason why rexx is not better choice. |

mortalkombat4,
That is precisely why CICS/DB2 or IMS/DB2 screens are for. With REXX the sql is always Dynamic and it involves a min of 4 steps , connect , prepare , execuete and disconnect which is not the case with Cobol.
