- NAME
- set - Read and write variables
-
- SYNOPSIS
- set _v_a_r_N_a_m_e ?_v_a_l_u_e?
- _________________________________________________________________
-
-
- DESCRIPTION
- Returns the value of variable _v_a_r_N_a_m_e. If _v_a_l_u_e is speci-
- fied, 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 pro-
- cedure unless the _g_l_o_b_a_l command has been invoked to declare
- _v_a_r_N_a_m_e to be global.
