Set DDE channel number

Syntax

Set DDE channel number {calculation}

Description

DDE command, Omnis as client. This command sets the channel number to be used in subsequent DDE commands. Each channel number identifies a particular conversation.

The channels are numbered from 1 to 8, and the flag is cleared if an invalid channel number is used. If you omit the channel number, it defaults to 1. The channel number selected can be the result of a calculation. All subsequent channel commands function on the current channel number. To select another channel, you must use a new Set DDE channel number command.

Example

Set DDE channel number {2}
Open DDE channel {Omnis|Country}
If flag false
  OK message {The Country library is not running}
Else
  Send command {Do method Invoice}
  Do method TransferData
End If
