Custom Messaging
There are two types of messaging modes, custom messaging and messaging mapping.
The custom messaging API is used to pass MotionSolve message directly to a user-written subroutine (MESSAGE_SUB). Messaging mapping is used to overwrite MotionSolve standard messages in the log file, or append your additional comments to the standard MotionSolve message.
Messaging API
MotionSolve calls MESSAGE_SUB at every instance when it accesses the log file.
