Publishes a message to all clients subscribed to a channel.

Syntax

procedure Publish(const aText, aChannel: String; const aGuid: String = ''; const aQueue: TwsQueue = queueLevel0);

Parameters

Name	Type	Description
`aText`	`const String`	Payload to publish.
`aChannel`	`const String`	Channel the message is published on; only clients subscribed to this channel receive it.
`aGuid`	`const String`	Optional Guid of the target server-side sgc protocol instance. Leave empty to use the default.
