RE: Efficiency of Bound vs. Dynamic Calls

If it is an interactive job with one or two calls per transaction, makes
little or no difference.  Batch job that call several times per record, for
thousands of records, big difference.  Prototype the procedure and create a
service program then bind it in, the difference is unbelievable.

Subject: Efficiency of Bound vs. Dynamic Calls






     Hello all

     I'm sure this issue has been covered here before, but as a newbie to
     the list, I'd appreciate any help.

     At my current place of employment they have created an ILE-RPG program
     to handle date manipulation, and standards state that this program
     must be used or all date manipulations.

     From OPM programs (which most of them still are), a regular CALL with
     parameter list is performed.  However I was surprised to see that in
     new ILE-RPG programs, they were still using a regular CALL.

     I suggested that a CALLB (bound call) would be more efficient.  They
     agreed, but stated that a dynamic call to an ILE program was quite
     efficient, so much so that making it a bound call would not gain
     enough to make it worth while dealing with the additional
     complications that this would entail.

     This didn't seem right to me, but I don't have any information to back
     me up.  Anyone got any thoughts on this matter?

     Thanks ....Norman
