Querying What Can Be Typed Next

When you are typing commands into a macro or into a command line, you may not remember exactly what arguments are available or what other commands are related.

You will find full details in the appropriate Reference Manuals to the module, but you can also ask the command processor what sort of command or commands it is expecting next by typing:

$Q

This will produce a list of every valid command word or argument type that you may enter next.

The list may be long and could include every valid command for the module that you are in.

The $Q facility is also useful to establish what is allowed as the next component of a command. Type the beginning of the command sequence followed by $Q.
