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()
