Category: Interprocess communication

Syntax:
// poking data:
DDE application topic item text

// executing a macro:
DDE application topic "" macro

// reading an item's value:
$DDE(application topic item)

// executing a macro and then reading an item's value:
$DDE(application topic item macro)

Performs a Dynamic Data Exchange (DDE) operation. The result of the operation, and the appropriate parameter values, depend on the application you're communicating with. application and topic must be single words; item must be quoted.

• Poking data - Sets the value of a data field.
• Executing a macro - Tells the application to run a command.
• Reading an item's value - Retrieves the value of a data field.
• Executing then reading - Combination of executing a macro and reading an item's value.

Example:
// tell ViRC to do something - double $ keeps it from being evaluated before DDE
DDE ViRC IRC_Execute "" Eval MessageBox My name is $$N.

// ask ViRC for the current time
@l $time = $DDE(ViRC DDE "IRC_ParseVars" $$time())
MessageBox ViRC says the time is $time.
