ismacro(arg1 [, arg2, ...])

Keywords: macros, general, variables
ismacro(arg) returns True if arg is a macro and False otherwise.  If arg
is undefined, ismacro() returns False.

ismacro(arg1, arg2, ..., argk) returns a LOGICAL vector, each element of
which is True or False depending on whether or not the corresponding
argument is a macro.

The principal use of ismacro() is in checking the arguments of a macro
for appropriateness.  See argvalue() for another way to check for the
properties of macro arguments.
