I have a friend who is writing a text based game, but as yet it had no save capabilities. I told him I'd right a save and load sub-routine for him because while im still new to it i know how to use filehandelers alot better than him.

Due to the simplicity of the game all that I need it to due is store variables in a text file from one running of the game until the next. The problem is I wanted the text file to be understandable instead of just a list of numbers so say the file (named test1.usr in a subfolder of the current directory named configs) is like this:

$a = 1
$b = 2

I am trying to figure out a way so that were I to run code like this:

print "enter username:";
chomp($uname=<STDIN>);
 $USERFILE='configs/'.$uname.'.usr';
open(USERFILE);
# Whatever the solution to my problem is
print $a + $b;

[download]
It would show up as: 
enter usename:test1
3

[download]
the only thing I can figure out to do is make the .usr file: 
1
2

[download]
with the perl: 
chomp($a = <USERFILE>);
chomp($b = <USERFILE>);

[download]
the only thing I can do with the current config (.usr) file is print it to STDOUT or another file. How can I keep the current formatting (and therfore legability) but still have the disired outcome.

P.S. this is a test version of the code. In the final it will be keeping track of actual information and will not just print 3. However, I bilieve the solution to this problem will work in the final version.
