Developing PML Code : Querying PML : Querying What Can Be Typed Next

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

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

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

The list may be long and could include every valid command for the module that the user is 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.
