Delay statement times are 64bit. 

In certain special cases, the compiler did not properly work with
long64 while handling delay statement times.

The same as %deassign above except this is used for real variables.
* %delay <delay>
* %delay <low>, <high>
This opcode pauses the thread, and causes it to be rescheduled for a
time in the future. The <amount> is the number of the ticks in the
time in the future. The amount is the number of the ticks in the
future to reschedule, and is >= 0. If the %delay is zero, then the
thread yields the processor for another thread, but will be resumed in
the current time step.
The delay amount is given as 2 32bit numbers, so that 64bit times may
be represented.
* %delayx <idx>
This is similar to the %delay opcode, except that the parameter
