<channel>
<ddelist>
The system flag will be set to TRUE and the errno (error number) variable will be
set to 0 if the command is successful, or FALSE and an error number other than 0 if
the command failed.
Up to four DDE conversations will be permitted if a <channel> variable is specified.
When a DDE connection is successfully made, the <channel> variable will contain
the ID of the conversation. If the connection was unsuccessful, <channel> will have
a value of 0 or -#, where # indicates the number of multiple sessions that would have
been started.
If <ddelist> is specified and the <channel> variable is -#, then <ddelist> will contain
a list of strings relating to each individual session that would have been started. Each
entry in the list will be separated by a comma, as follows:
szAppName1|szTopic1,szAppName2|szTopic2
You can list the available topics for an application by specifying an empty string for
the <topic> entry and including the <channel> and <ddelist> variable names. The
following example will cause a list of available topics for the application Excel to be
stored in the variable ExcelTopics:
dde initiate "Excel" "" channel ExcelTopics
