Comments
Assert: Allocates server resources so server can respond to signals from the signal
block.
Deassert: Deallocates resources associated with the signal block.
The signal block must be enabled prior to use. If not, all other signals will produce
the following error:
Object not loaded.
The only exception to this rule is the Shortcut signal which “auto-enables” the
e-mailer signal block for the duration of the signal. (If it was already enabled when
the Shortcut signal was issued, it remains enabled after the signal is processed;
otherwise it is disabled.) Demo 1 depends on this feature.
Two special situations are noted below:
(1) Referenced scrollers are auto-enabled:
When a scroller signal block is referenced* by a another signal block, it is
automatically enabled when the referencing signal block is enabled. Therefore,
the Enable signal of such a scroller signal block should not be connected to
anything.
(2) Standard Scrollers’ Enable signal is non-functional:
In fact, although the Enable signal of a Standard Scroller signal block is
defined, it is ignored by the server.
†
The reason the signal is defined even
though it cannot be used is that it can however be used from the Signal
Analyzer window (for debugging purposes).
____________________
* Examples of “referenced scrollers” are the optional message and recipient scrollers of an
e-Mailer signal block; or the optional IN box and body text scrollers of an e-Mailbox signal
block.
†
This prevents the scroller from being used for general purposes — for which a database
license is required.
