Re^4: Filter and writing error log file

I have one loop related question. I have defined an array of alphabet from ("A" .. "Z") but after reading a long file the alphabets end and the program shows error of uninitialized values.

My questions is how can I define an array of alphabets which can go to AA, BB, CC and ...so on when the "A" .. "Z" ends.

Alphabet stands for the whole series of letters. Use the word "letter" for a single character like "A" or "Z", please, not alphabet. Don't create an array. Just start with `my $letter = 'A';` [download] In every iteration, do `$letter++;` [download] and let the magic do all the work. لսႽ† ᥲᥒ⚪⟊Ⴙᘓᖇ Ꮅᘓᖇ⎱ Ⴙᥲ𝇋ƙᘓᖇ	[reply] [d/l] [select]

Thanks for explaining the '^' behaviour and loop through the letters. I have some more doubts and questions regarding one of my another programs which I have written but its very crude and i want some help in making in more robust. Is it ok to post it here and get some help. Thanks	[reply]
