I am really sorry for the misunderstanding my question created. I am writing a syllable structure checker with a search pattern given as an input, for example CVC for BOB or CCVVCV for Sheila, where C stands for a consonant and V for a vowel. Consonants and vowels for different languages are stored in separate arrays.

Since there are thousands of possible combinations, I though about assigning a separate numbered variable for each letter read from the input and use them afterwards in foreach structures, for example:

foreach $c1 (@consonants) {
    foreach $v1 (@vowels) {
        foreach $c2 (@consonants) {
            foreach $v2 (@vowels) {
                print FH "$c1$v1$c2$v2\n";
            }
        }
    }
}
