Dynamic Minimum Balance in DRP500

[Bill <brobins3d@xxxxxxxxx>]

405CD environment.

After journaling our CIC file to determine which program is changing the 
Minimum Balance and a few other fields, DRP500 was determined to be the 
culprit.

Looking at the code, I see where the minimum balance field is updated at 
the end of subroutine $DBAL.  I figure that we have some kind of 
error/out of sync condition that causes this routine to perform the 
re-calc but I haven't delved into it because it gets quite confusing.

Does anyone know the data circumstances under which the program should 
properly re-calc the item's minimum balance?  This may help me to 
determine why it's being erroneously called.
