The return -value from \fBcatch\fR is a decimal string giving the -code returned by the Tcl interpreter after executing \fIscript\fR. -This will be \fB0\fR (TCL_OK) if there were no errors in \fIscript\fR; -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 -\fIvarName\fR argument is given, then it gives the name of a variable; -\fBcatch\fR will set the variable to the string returned -from \fIscript\fR (either a result or an error message). -.PP -Note that \fBcatch\fR catches all exceptions, including those -generated by \fBbreak\fR and \fBcontinue\fR as well as errors. - -.SH KEYWORDS -catch, error |
