You'll have to learn it if you want to use it. I couldn't think of any other alternative.

Arrays in Perl have zero-based indexes. $F[1] is the 2nd element, which corresponds to the 2nd column of your file. On the same lines, $F[24] refers to the 25th element and $F[34] to the 35th.

NAME
towupper, towupper_l -- lower case to upper case letter conversion (wide character version) LIBRARY
Standard C Library (libc, -lc) SYNOPSIS

The towupper() function conforms to ISO/IEC 9899:1999 (``ISO C99''). BSD
