in reply to Can't use string "1" as a HASH ref while "strict refs" in use

one of those is simply a scalar. to find out which add this code precursing that line

print "ref of switchnum = ref($switchnum) \n ref of calltype = ref($calltype) \n";
The one that is ne "HASH" is your culprate

    Let's try:
    my $switchnum = 15; my $calltype = []; # Empty array ref print "ref of switchnum = ref($switchnum) \n ref of calltype = ref($calltype) \n";
    It prints:
    ref of switchnum = ref(15) ref of calltype = ref(ARRAY(0x1234567))


    Guess what: you can't interpolate functions that way :)

    Try this one:
    ref(eval "\$$_") or warn "\$$_ is not a reference" for qw(switchnum ca +lltype);
