Dmitry,

*From*: Sampled values of a variable, of a constant cast expression and of
sequence methods defined as described above
*TO: *Sampled values of a variable, of a constant cast
expression*,* andof sequence methods defined as described above

"As an illustration consider two bit variables a and b, where a is a regular
variable and b is a free variable. Let both variables change in a time slot
t1 from 1’b0 to 1’b1. If the sampled values of these variables in time slot
t1 are referred from another time slot t2 then the sampled value of a will
be 1’b0, whereas the sampled value of b will be 1’b1 – the sampled values of
these variables in the Postponed region of t1."
[Ben] Dmitry, I am having trouble understanding this end qualifier "the
sampled values of these variables in the Postponed region of t1 ".
You're saying that time slot t2, the sampled value of b is 1'b1.  The way it
si written, it sounds like you're that t2 takes the value of its Posponed
 region of t1, which is not known since t2 is before the Postponed region.
I believe what you are saying is:
*TO: *If the sampled values of these variables in time slot t1 are referred
from another time slot t2 then the sampled value of a will be 1’b0, whereas
the sampled value of b will be 1’b1, which represents the sampled values of
these variables in the Postponed region of t1."
