- NAME
- foreach - Iterate over all elements in a list
-
- SYNOPSIS
- foreach _v_a_r_n_a_m_e _l_i_s_t _b_o_d_y
- _________________________________________________________________
-
-
- DESCRIPTION
- In this command _v_a_r_n_a_m_e is the name of a variable, _l_i_s_t is a
- list of values to assign to _v_a_r_n_a_m_e, and _b_o_d_y is a Tcl
- script. For each element of _l_i_s_t (in order from left to
- right), foreach assigns the contents of the field to _v_a_r_n_a_m_e
- as if the lindex command had been used to extract the field,
- then calls the Tcl interpreter to execute _b_o_d_y. The break
- and continue statements may be invoked inside _b_o_d_y, with the
- same effect as in the for command. Foreach returns an empty
- string.
