As you'll doubtless know there are several core routines used in Basic+ to interact with OI forms, probably the three most important being:
To maximize performance when dealing with properties it is common practice to pass @rm-delimited arrays to Get_Property and Set_Property like so:
A recent support query from one of our clients was to enquire if the Send_Message() function also supported a similar interface, and unfortunately the answer is no - it does not accept @rm-delimited arguments when invoked.
However the question did trigger a distant memory that led me to dig up a very old email thread from many years ago between ourselves and developers at Revelation, during which a similar capability was discussed and implemented, but alas, it appears, never documented.
Whilst Send_Message() itself doesn't support @rm-delimited arrays of message data, the Set_Property() function does support a "SEND_MESSAGE" property which can be used in a similar manner - you simply wrap the message name and arguments into an @fm-delimited array and use this as the new property value to set.
e.g.
Notice the convert statement in the code above - if you use any system delimiters in your message arguments (@fm,@vm,@svm,@tm) then you must convert them down a level, because the SEND_MESSAGE property will convert them up a level before executing the message internally.
In this way we can duplicate the stacking behaviour of Get and Set_Property for Send_Message.
- Get_Property()
- Set_Property()
- Send_Message()
