errclear

Description

clears the action (error-handler) connected to error of type n.

If n is positive (n > 0), it is the number of the cleared error ; otherwise if (n <= 0) all errors are cleared (default case).

Examples

a = 1;
            b = undefinedvariable + a;
            lasterror()
            b = undefinedvariable + a;
            errclear()
            lasterror()
            b = undefinedvariable + a;
            errclear(5)  // error 4 always as last error
            lasterror()
            b = undefinedvariable + a;
            errclear(4)
            lasterror()
