- The _w_h_i_l_e command evaluates _t_e_s_t as an expression (in the same way that
- eeeexxxxpppprrrr evaluates its argument). The value of the expression must a proper
- boolean value; if it is a true value then _b_o_d_y is executed by passing it
- to the Tcl interpreter. Once _b_o_d_y has been executed then _t_e_s_t is
- evaluated again, and the process repeats until eventually _t_e_s_t evaluates
- to a false boolean value. CCCCoooonnnnttttiiiinnnnuuuueeee commands may be executed inside _b_o_d_y
- to terminate the current iteration of the loop, and bbbbrrrreeeeaaaakkkk commands may be
- executed inside _b_o_d_y to cause immediate termination of the wwwwhhhhiiiilllleeee command.
- The wwwwhhhhiiiilllleeee command always returns an empty string.
