case RHS_SUBS then case RHS_SUBS_CHECK then case RHS_SUBS_I then opRHS_SUBS() break
case RHS_SUBS or RHS_SUBS_CHECK or RHS_SUBS_I then opRHS_SUBS() break
So, the two above are identical?
Kind of ... except that we don't allow 'or' or 'and' in the case clause, and only if the first example has the "with fallthru" on its switch statement. However below are equivalent ...
switch with fallthru do case RHS_SUBS then case RHS_SUBS_CHECK then case RHS_SUBS_I then opRHS_SUBS() break
switch do case RHS_SUBS, RHS_SUBS_CHECK, RHS_SUBS_I then opRHS_SUBS()
Note that by default, that is if you do not put the "with fallthru" modifier in, then switch works like you thought it would. It does NOT execute anymore than one case clause. If you really want it to execute multiple case clauses you must also add the "with fallthru".
