DDE message syntax
DDE messages employ a syntax consistent with that used by VTel, the Telephony DDE
Server, and other CORBA-based components. The syntax is similar to a function call,
consisting of a command name with a list of arguments enclosed in parentheses and
separated by commas. The entire command is enclosed in square brackets and may be
suffixed by a request identifier:
[command(arg1,arg2,arg3...)]
[command(arg1,arg2,arg3...)][request_id]
Command name
The command name may contain any combination of the characters A-Z (uppercase or
lowercase), 0-9, underscore (_) and period (.). Commands cannot start with an underscore
or digit. Separate elements of commands with periods.
