- catch script ?varName?
-
-
- DESCRIPTION
- The catch command may be used to prevent errors from abort-
- ing command interpretation. Catch calls the Tcl interpreter
- recursively to execute script, and always returns a TCL_OK
- code, regardless of any errors that might occur while exe-
- cuting script. The return value from catch is a decimal
- string giving the code returned by the Tcl interpreter after
- executing script. This will be 0 (TCL_OK) if there were no
- errors in script; 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 varName
- argument is given, then it gives the name of a variable;
- catch will set the variable to the string returned from
- script (either a result or an error message).
