This configuration file option sets the maximum number of branch "levels" that you can have in a Tango application file. This applies to Branch actions that have the Return option set. It specifies the number of returns that can be outstanding at any time. If this limit is exceeded during an application file execution, an error occurs.
This configuration variable also specifies the number of call method "levels" when method calls are made on Tango class files, which in turn call other Tango class files.
The default value is 20. Setting this configuration variable to a larger value may increase the memory requirements of Tango Server.
