Hi,
I have a program which takes an input file that includes a string which tells the program which subroutine to use (from an imported file of subroutines, using the "do" statement) at a certain point.
(The input file changes through the day, so different subs are needed at different points).
I save the imported string as
my $generic_sub ="name of sub to use"
Then, at the point in the program when I want to use the sub, call
$return value = &$generic_sub(arguments)
Problem: using strict this throws the error:
Can't use string ("name of sub") as a subroutine ref while "strict ref
+s" in use at program_name_1.0 line 153.
I've read the perlref docs about using references to name subroutines, but that doesn't seem to solve the problem, in that I still need to use the name of the string from the input file to determine which subroutine to use, whether that subroutine is referred to by a reference or not. And it is the use of the string as a subroutine ref that is causing the error, right?
Thanks for any pointers.
Colin
