in reply to Problem with while loop
Hopeless, yes, the code is a mess, but the situation is not as hopeless as your nick would imply. Before we can help you, we need to know what you are looking for. A quick check shows that your code compiles cleanly, so it's not an obvious syntax error. What we need to know is:
- What sort of input is your script using? (a small sample, please)
- What output do you want?
- What output are you actually getting?
Without clear information like that, most of the advice that we can offer is a shot in the dark. However, there are two pieces of advice that I can give right now. First, use strict. All competent Perl programmers will tell you that for a program of significant size, you should almost always be be using strict. Strict will allow you to catch a lot of the typos and other problems which might plague your code (and it did, when I used it for your program.
Second, turn on warnings. If you are using a shebang line, add a -w to the shebang line:
#!/usr/bin/perl -w
If you are using Perl version 5.6 or better (I think that's when it was introduced), you can add "use warnings; to your code.
Just turning on warnings in your code produced some interesting information:
C:\temp>perl -wc index.pl Name "main::ccdrive" used only once: possible typo at index.pl lin +e 4. Name "main::name" used only once: possible typo at index.pl line 6 +8. Name "main::rephash" used only once: possible typo at index.pl lin +e 158. index.pl syntax OK
As for the command line switches, -w enables warnings and -c tells Perl to compile the program without running it. This is a quick check to see if the program can even attempt to run.
The first warning refers to this line:
$ccdrive = $ENV{CC_DEFAULT_DRIVE};
Since that variable is not used anywhere else in the program, I wonder if this is part of a feature you have not yet implemented?
The second warning refers to this:
$name=$hash{"Tag"};
Later, you have the following statement twice: push(@vobs, $vobname);. Since $vobname is not initialized anywhere, perhaps the initial assignment should have been to $vobname instead?
The third warning is what may be causing your issue. It refers to the following line:
print TFILE2 "<font color=\"$rephash($ABC[$idx])\"><td> $ABC[$idx] +  </td> ";
Even though you've already declared a %rephash, it's not going to get recognized here because you need curly braces instead of parentheses. Also, needs a semicolon at the end. Here's a revision of that line:
print TFILE2 "<font color=\"$rephash{$ABC[$idx]}\"><td> $ABC[$idx] + </td>";
In a similar, previous line, you have an error that's not reported:
print TFILE2 "<font color=\$rephash{$replica}\> <td> $rephash{$rep +lica} $DEF[$idx] </td>";
The problem there is that you put a backslash directly in front of the dollar sign. When you do that in a string, it tells Perl that you really wanted to print a dollar sign and didn't want the following variable interpolated. The following line is what you intended:
print TFILE2 "<font color=\"$rephash{$replica}\"> <td> $rephash{$r +eplica} $DEF[$idx] </td>";
Hope this helps.
