Maybe I wasn't clear so people took the "die" command too literally.
There might not be a "die" command in the code at all. It might be
a subroutine that calls "die", or some statement that causes a runtime
exception, or any other means of raising a normally-fatal exception:
eval {
# Code where an error may occur
exception_causing_method();
# Code where I want to resume after handling the exception
print "Continuing....\n";
};
I want to handle the exception and then resume execution at the following
line, regardless of how the exception is caused. Can anyone recommend a
technique to do this type of resumptive exception handling in perl? I
suspect it involves something more complicated than an eval {BLOCK} form.
Thanks.
