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.
