My main loop is iterating forever i.e. a daemon; thus, any code after the

If the string is really "5 - 4", and you get

Any ideas ?
Thanks in advance

The code is as follows :
Adding one and incrementing are different. You're adding 1. Did you try
incrementing the character?
Instead of this:
$code[$y]=$code[$y]+1;
try
($code[$y])++;
#!/usr/bin/perl
@code = qw( A B C D );
$y = 0;
if( $code[$y] ne "F" ){
print "$code[$y]\n";
($code[$y])++;
print "$code[$y]\n"
You are right, $code[$y]=$code[$y]++; shouldn't work, since it increments
after the assignment.
$code[$y]++; works for me, as does $code[$y]=++$code[$y];
This code:
@code = split //,"ABCD";
#values stored in @code are now A B C D
$y=0;
if($code[$y] ne "F"){
print "$code[$y]\n";

Oh, wait. I misread that.
Are you sure the array contains letters? Usually an array will return 1 for
an increment when the previous value was '', 0, or undef.

Play with it. The more you play the better you will get, (just not too much
or you'll go blind).
Good books are:
Perl by Example (the Example books are an excellent place to START)
Perl in a Nutshell
Also it takes time. You will not learn everything in 24 hours like some
books advertise.
