// REBUILD_EVENT() rebuilds the event table for
// variables modified in the same block of code in which
// it resides.
//
// With no braces, a REBUILD_EVENT() in DEFINE_START
// should rebuild the event tables that use any variable
// modified in DEFINE_START, above the REBUILD_EVENT()
// statement.
// You can reduce the scope of the REBUILD_EVENT() by
// delineating a block with braces:
DEFINE_DEVICE
dvTP = 10001:1:0
DEFINE_VARIABLE
INTEGER X // loop counter
INTEGER nBTNS[4000]
DEFINE_START
FOR (X = 1; X <= 4000; X++)
{
nBtns[X] = X
}
// the braces below enclose a variable update and
// rebuild_event statement in a single block
