Thanks for your detailed replies Bruce and Sean.

s> do("wait for",RefreshDelay++","++NeverTrue)

Great -- that works here :)
After reading that, I discovered that this also works:

do("wait for",RefreshDelay)

which is consistent with Help:
wait.for (n)

The only reason I added a second argument "NeverTrue"
was trying to tell wait.for that the first expression
represents the number of microseconds.

s> However, "wait until" seems to not work in this syntax.

Yes wait.until seems to be more limited in where you can use it.
In some places it tends to produce multiple error messages
requiring that PowerPro be killed and restarted.

Anyway, do("wait for",RefreshDelay) will be perfectly OK
for the situation I was trying to fix.

Now that I know there is a workable solution, IMHO there is
no need to change the syntax.

Thank you

Alan
