- The ccccaaaattttcccchhhh command may be used to prevent errors from
- aborting command interpretation. CCCCaaaattttcccchhhh calls the Tcl
- interpreter recursively to execute _s_c_r_i_p_t, and always
- returns a TCL_OK code, regardless of any errors that might
- occur while executing _s_c_r_i_p_t. The return value from ccccaaaattttcccchhhh
- is a decimal string giving the code returned by the Tcl
- interpreter after executing _s_c_r_i_p_t. This will be 0000 (TCL_OK)
- if there were no errors in _s_c_r_i_p_t; otherwise it will have a
- non-zero value corresponding to one of the exceptional
- return codes (see tcl.h for the definitions of code values).
- If the _v_a_r_N_a_m_e argument is given, then it gives the name of
- a variable; ccccaaaattttcccchhhh will set the variable to the string
- returned from _s_c_r_i_p_t (either a result or an error message).
