Fundef

Function: fundef (<f>) Returns the definition of the function <f>.

The argument may be the name of a macro (defined with ::=), an ordinary function (defined with := or define), an array function (defined with := or define, but enclosing arguments in square brackets [ ]), a subscripted function, (defined with := or define, but enclosing some arguments in square brackets and others in parentheses ( )) one of a family of subscripted functions selected by a particular subscript value, or a subscripted function defined with a constant subscript.

fundef quotes its argument; the quote-quote operator defeats quotation.

fundef (<f>) returns the definition of <f>. In contrast, dispfun (<f>) creates an intermediate expression label and assigns the definition to the label.
