by a "subroutine" statement are local to the current macro (or macros called

command. User-defined commands defined by "subroutine" or "command" state-

The statement "command" without parameters gives a list of all user-defined
commands, and indicates where they are defined.

Description

Defines a new user-defined command within a macro, i.e. a macro within a macro. User-defined commands defined by subroutine statements are called by their name, possibly followed by parameters, in exactly the same way as macros. User-defined commands defined by a subroutine statement are local to the current macro (or macros called through it). Within a macro, a user-defined command can only be called after it was defined.
