Hello
First of all, I apologize if this is not the right list to ask my question,
but as I am a perl beginner, I think it is the most suitable list for me
:o)
So here goes my question:
I have a main program which will call a subroutine, say "S", belonging to
another module. The question is that there could be several modules that
contain a subroutine also named "S", which basically will return equivalent
values to the main program.
My problem is that I don't want to harcode the name of those modules (for
example using an "if"), because I don't know a priori how many there
will be
or which will be needed to call at any moment. The idea is that there will
be a file in which the main program could read which module is necessary in
each moment, and so call it.
So the question is: Is there any way to call a subroutine without
explicitly
writing his name?
Thanks in advance, and if I haven't been able to explain it well, please
ask
me :o)
Regards
Ana
It sounds like the module names are variable, but the subroutine name is
constant. If so, you can write the subroutine to behave like a method
and call it thusly:
$modulename->subname();
Of course, you would get the correct module name into $modulename first.
