perl - how can we name a variable base on value of another variable

Hey all,

perl - how can we name a variable base on the value of another variable?

for example in ksh/bash we do :

export c="100"
export x`echo $c`=2000
echo $x100
x100=2000

is it possible to do something similar for perl?

I already tried many ways but nothing is working.

I am trying to solve a issue in an perl script and the solution that i am trying to do should have different variables.

Can someone please help me on this?

Thanks in advance.

you can do it with a hash ref:

my $hashref = {};
$hashref->{var1} = 'val1';
my $var1 = $hashref->{var1};
$hashref->{$var1}= 'val2';
my $var2 = $hashref->{$var1};

print "KEYS:\n";
foreach my $key (keys %$hashref)
{
	print "key=".$key."\n";
}
print "\nVALUES:\n";
print "var1=".$var1."\n";
print "var2=".$var2."\n";

this results in

KEYS:
key=var1
key=val1

VALUES:
var1=val1
var2=val2
perl -e 'my $x= 100;
> ${x.$x} = 2000;
> print "$x \n";
> print "$x100 \n";
> '
100
2000

Note: This is not a standard method of doing. When requirement like these arises it is preferable to use hashes

Cheers
