5.7.3 until control statement
The until keyword suspends the execution of the program until the specified
expression has a false value (0).
Syntax
until(expression)
Example:
function foo()
// do something
……
until(g_var>0) // program wait until g_var >0
end function
5.7.4 TRACE control statement
To send messages from the virtual machine to Elmo Studio uses a program statement
with a TRACE keyword. The Elmo Studio is the standard IDE for development and
debugging of MAXL programs. If Maestro’s virtual machine comes across a statement
with TRACE during debugging MAXL programs, an Elmo Studio output window
appears with a TRACE message.
5.7.5 reset control statement
The reset keyword is used to restart the program. After a program reaches a reset,
program flow will be restarted from the next run function. At the same time the entire
call function stack resets.
5.8 Difference Between Static and Dynamic Group
The Maestro supports both static and dynamic group. Table 5-8 below describes the
differences between the two groups.
Table 5-8 Static and Dynamic Groups

created only if all nodes of
the group exist

always independently of the
amount switched-on nodes in
the group.
Size of group
