SYNOPSIS

closure symbol_variable(string arg)
closure symbol_variable(symbol arg)
closure symbol_variable(int arg)

DESCRIPTION

Constructs an identifier (lfun) closure from the global variable arg of this_object(). The variable may be given as a symbol, by name or by its ordinal number in the objects variable table.

If there is no such variable, or if it is not visible outside the object, 0 is returned.

If the argument is an integer, and the variable is inherited and private in the inherited object (i.e. hidden), then a privilege violation will occur.

HISTORY

Enabled since 3.2.1@8
