Significance of DISC40=5,40=B and 59=2 for mkt and Limit

Imported from previous forum

Hi Everyone,
I would like to know the significance of these things.
Say MarketOnClose with DISC means what , is this a correct business scenario. Is it possible for trader to submit the order to market in the fixed closing time. same for limit on Close. On Opening should also happen in a very quick execution time when the mkt opens, does trader can work on these.

I thikn that for these only the DMA / FOK is the valid case.

Please suggest.
