Returns the value of variable _v_a_r_N_a_m_e. If _v_a_l_u_e is
specified, then set the value of _v_a_r_N_a_m_e to _v_a_l_u_e, creating
a new variable if one doesn't already exist, and return its
value. If _v_a_r_N_a_m_e contains an open parenthesis and ends
with a close parenthesis, then it refers to an array
element: the characters before the first open parenthesis
are the name of the array, and the characters between the
parentheses are the index within the array. Otherwise
_v_a_r_N_a_m_e refers to a scalar variable. If no procedure is
active, then _v_a_r_N_a_m_e refers to a global variable. If a
procedure is active, then _v_a_r_N_a_m_e refers to a parameter or
local variable of the procedure unless the _g_l_o_b_a_l command
has been invoked to declare _v_a_r_N_a_m_e to be global.
