Discounted Bonds in Securities

Hi,

Can someone please validate my understanding on the set ups and interest calculation on bonds?

1) For normal interest bearing bonds (field PRICE.TYPE in SECURITY.MASTER is set to BOND), after we run COB system will post the accruals. What will be the entry? is it categ n spec? and how do i see the entries ?
2) For zero coupon bond, my understanding is interest.rate in SM should be zero, but we have to give a value in the field ISSUE.PRICE which is less than what we give in REDEM.PRICE in SM. System should accrue the interest of the difference amount. What is the calculation of accruals in that case? n where do i see the entries?
3) What is the calculation of accruals when the field PRICE.TYPE is set to DISCOUNT?
4) How is yield calculated? There is a field in SM, DISC.YIELD.PRICE how do i confirm the value which gets defaulted in that field
