- 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).
-
- Note that ccccaaaattttcccchhhh catches all exceptions, including those generated by
- bbbbrrrreeeeaaaakkkk and ccccoooonnnnttttiiiinnnnuuuueeee as well as errors.
