Simple Yet Annoying Problem

[chitownclone]

A variable in my program is an AE Code ($aenum) that contains both numbers and letters, which are assigned via .dat file. Example $aenum is c15, c16, c17.

However, I can't get my if then to work and error when a newly input AE code is the same as an existing.

If ($aenum eq $aenum2) {
ERROR;
}

Use == works fine if its numeric, eq works fine if its all letters...but what do I have to do to make eq or == work when the variable contains both letters and numbers??

Thanks

eq should work for both, perl does not 'type' its variables so if you compare to numbers using 'eq' perl will do a string comparison and come out properly.

Hi chitownclone, are you making sure there's no trailing or leading whitspace either end of the strings you're comparing?

        s/\s+$//;
    }
    return wantarray ? @out : $out[0];
}
