DMSII - LOCK statement - Query

DMSII - LOCK statement - Query

Hi all ,

I came across a scenario similar to the one below in one of the programs I am analysing...

LOCK abc-set AT vara = '1' and varb = '2'
On exception

LOCK NEXT abc-set
On exception

MOVE 'A' to varc


abc is the dataset, abc-set is a set , indexed by vara & varb and varc is a column of the dataset.

Does this mean that ALL the records satisfying the condition mentioned in the first LOCK statement is updated with value 'A' in varc ?
