Whilst there may no longer be any performance benefit in converting to this syntax, an IN clause can make a complex READ statement more readable (no pun intended).

Consider the example below:

This can be re-written using IN clauses:

Even better, the improved READ EACH statement above was automatically converted by using a VerifIEr check that detects READ statements that could use an IN clauses and then invokes the integrated genIE fix to convert the READ statement.
